#4 identification help?

[points]

For all you #4 serial # gurus. I picked up a Mk1 barreled action the other day. It's in pretty rough shape but I snagged it for $20 and thought it might at least make a good paper weight. Here's the thing
Its stamped #4 Mk1, not penciled. serial E28644A I thought the "E" would make it a BSA Shirley but the #s seem to be Faz. The "A" should mean non interchangable parts used
Then the hard part. The receiver ring has a very nice C Broad Arrow stamped on the right side. Barrel # matchs the action also.
So what is it and why the LB stamp
Thanks

A couple picture's are worth a couple 1000 word's.

...more like a couple of million words.

I've seen Brit guns with C Broad Arrows on them quite a few times.

A "C Broad Arrow" is not a Long Branch stamp. It is a Canadian government property ownership stamp,

Right you are. Brain fart on my part. It is the first Brit I have seen with a Canadian stamp
Thanks Guys.

Did Brit made No.4's find their way into Canadain service? Or did they have a system the inspected them for LB/Savage production?
