I'm still working on putting a Central sight on my '56 Faz No.4 Mk.2, and today received the sight base adaptor from Tiriaq. (thanks Tiriaq! The money order will be in tomorrows mail. Really.)

It will mount to the trigger guard bolt at the bottom and the safety bolt up top, in the upper left countersunk hole, but the existing trigger guard bolt is too short:

I need a longer trigger guard screw: I figure at least 25mm long. These apparently are threaded in British Associated threads, and the size for this is 4BA.
As for the safety lever bolt:

There's a thread about this over at gunboards: http://forums.gunboards.com/showthread.php?t=118105
But I'm not clear as to whether I need a longer bolt here or not. It appears that the adaptor plate will take the place of the safety spring block:

Have I got that right? And that the addition of a simple coil spring between the switch shaft and the adaptor plate will keep the safety switch from moving.

Up at the front end, I'm trying to mount this foresight: (can anyone identify the make of this by the way? )

It uses these inserts:

...and unless someone has a specific adaptor for it, does anyone have a spare dovetail that I can modify to accept my foresight? Specifically, I'm looking for the part that says "pat pend", as I don't want to screw up the existing one:

You can see from this pic:

...that the sight block is slanted forward; I'll level it off and cut a level slot across its side to accept my sight. My sight will almost grip it, but not quite. In order to remove the existing dovetail, does anyone have the front sight blade securing screw tool to back off the larger screw seen here:

Or should I try to make my own?

Any advice/sources/comments are most welcome.
 
If I was you I would get a Parker Hale tunnel sight that was intended for the No4, sure make things a lot easier and you wouldn't need to alter the rifle. (it may even take the same inserts)

Also, you can easily make a tool to remove that PITA grub screw. Something like this:

For the screws, you should contact this guy: ht tp://www.customscrewsandmore.com/default.html

Hey, if you have one spare front sight insert, any type, and you wouldn't mind parting with it, I'd gladly take one - I have a insert-less front sight on one of my rifles!

Interesting front sight that is on the rifle, I've never seen one like that.

If your going to use the one with inserts I would suggest that you get another front sight base to modify. Save the one thats on the rifle.

Should be easy to find a solid base without the screw to modify, I think I have a few kicking around. :D

Thanks for the suggestion, VR. I guess I'll try the EE for a PH sight like that. Do you have a model number? I'll see what tools I have that I can modify for that grub screw.

Thanks Lou for that website. I tried that link over at gunboards, but it wouldn't work. I'll have a boo at my inserts, see what I can spare you. PM me your address.

I plan to keep the existing one, for sure. If you've got a spare solid base that fits a No.4 Mk.2, PM me- I have a feeling I may need it! :D

I think Garlochian makes a tool for it too. He has a post it the EE.

Their are a few different models for those sights. I think PH made a couple and later AJ Parker did as well. They pop up on eBay from time to time. I sold one a while ago, they can be acquired for reasonable cost, I'm sure someone here has a spare for you.

The models I know of are: PH Model FS22, PH Model FS 22D (short version), AJP Model 2.

Excellent! Just the info I need- thanks again.
 
I have a line on an AJ Parker Model 2 foresight, but I'm now seeing a problem that I should have seen before. The dovetail on the sight block is canted forward, and any foresight with matching dovetail would be canted forward as well.
Depending on the length of the foresight, this may not be an issue, but it sure would look dopey as hell. Woodchopper, is that what you meant by "Interesting front sight that is on the rifle, I've never seen one like that."?
Is this a "Canadian pattern" front sight block? And do I need a "solid type" front sight block with a level dovetail? Sure looks like it to me.
Anyone got a solid type block/band assembly or something with a level dovetail?

The tunnel sight should sit straight in the foresight block, despite the forward cant. It looks like it won't but if it's the correct tunnel sight for the No4 it will, IIRC the dovetail base on the tunnel sight is slightly offset to account for the tilt. At least the one I had was.

What I believe woodchopper was referring to was your front sight blade itself which has a screw in the front of it. I've never seen one with a screw in it either. It looks to me like you can adjust the height of the blade on that one. Must be a special one for match rifles or something. Normally they look like this:

You have a MkI foresight block, the solid MkII version still has a forward cant. They're identical, I just checked to be certain.

The ones that Parkers used with their proprietary match foresight were modified from the solid [wartime utility type] block.

I sometimes buy in some of these when I can find them, and usually have to do some selective assembly to get a combination that fits best.
I don't know what that globe foresight you've got is for, but it's probably a commercial T.R. barrel with an integral block.

I've seen a Brindles kit with interchangeable foresight elements in a modified military blade base.

Interesting. The sight block you've pictured is clearly level. Do you have one for sale that will fit my No.4 Mk.2? Oh well, as I said, if the AJP2 foresight doesn't work, I'll flog it.
You're right about the integral block; I took it off a Grunig when I switched to F-Class, and decided to use it on my No.4
 
This was a picture from some time back that's been hanging around in the PC, just for queries like this. I don't presently have any of the base in stock, though I will be looking out for some.
 
Interesting, the dovetail on that one is a completely different size. Sorry to mislead you stevebc, if it doesn't work I'll buy it off you for being responsible. The problem is I know there is a tunnel sight for the normal sight blocks - and I assumed they'd all be the same, I should know better now then to assume, there's always exceptions. I suspect the earlier models are the ones that fit the standard No4 sight blocks, but I don't know which model number they are. If anyone has one please post a picture of it, I unfortunately can't seem to find any pics of my old one. I send a PM to the guy I sold it to, so hopefully he still has it and can take a picture.
 
There is a tunnel sight that was made by Parker Hale with the appropriate sized dovetail and angle to fit the standard military sight block on the No4. The block that MK V11 is showing was also available for the Matchmaker tunnel sight. You have to find both or just the tunnel sight and machine the slope off the base and open the dovetail to suit. To use the sight block shown in the original post you need to replace the sight block. I've seen this done however it could get pricey.

HA! See if I trust you again! :D

Ah well, ain't none of us perfect. It wasn't expensive, and I'm sure I'll be able to flog it, but thanks for your kind (guilt laden) offer. Do you feel terrible yet? :p
 
Well, now that VR has shown himself to be suitably repentant :p, back to my search- which is to ask you lot if you'd have a look through your stuff for a spare sight block band, solid or not, level or not, to fit a No.4 Mk2. I'm stuck until I can get one, as I don't want to play silly buggers with my existing block.
Question, would this part also fit other marks of No.4's?

Meanwhile, I'll go post a wtb in the parts and bits forum. My thanks in advance.
