i picked up this rifle receiver for a sporter build i have in mind, but im not sure what it is exactly, im assuming its a m98 large ring.

will just a standard 98 bolt fit this receiver?

i believe this is a Modelo 1907 made for Paraguay

this is what wiki says about it
"The Models 1904 and 1907 were similar to the Gewehr 1898. They featured a longer cocking piece. Only the rifles made for Paraguay kept the Lange Vizier sight of the German rifle.[1][2] While most of the rifles were fitted only with a short bayonet lug that required a bayonet with a muzzle ring,[3] rifles ordered by Paraguay and Ecuador had another lug to fit the Mauser Model 1895 bayonet"

The intermediate length is referring to the size of the action - the bolt will be slightly shorter than a standard 98. Other parts, like triggers, might be the same, but bolt body, extractor, firing pin, possibly cocking piece and shroud are found in both "standard" and "intermediate" length mauser 98's.
 
From Ball's "Military Mausers of the World" 5th edition, pp. 273-275, the Paraguayan Modelo 1907 would have been chambered in 7.65x53. It was made at Oberndorf - same as yours - and was received as both rifles and carbines. No mention that I could find regarding the action's length. Do you have another mauser's bolt to try in it?
 
Thanks a lot for the info guys. Very helpfull.

I only have a zavasta mauser in 460 right now. No other bolts to try. It came with the stock, bottom metal and all that. Just missing the bolt.

Ill post an add for a intermediate mauser bolt on the EE

"the Paraguayan Modelo 1907 would have been chambered in 7.65x53. It was made at Oberndorf " yes this is the rifle in question
 
This is what you have. It's about .250 inches shorter than a standard length K98.

Boyd's gunstocks used to have finished stocks available. Many of these rifles were chambered in 7x57 but IMHO, the 30-06 would be to long and would require extensive mods to work properly. These would include mods to the mag well and action. Anything the same or less than the length of the 7x57 will work fine.

I'm going to throw this out to you and you may not like it.

What you have is a bare bones surplus, barreled receiver that looks to have been drilled and tapped for what will likely be hard to find and expensive scope mounts. If you insist on a sporter stock add C$400 to the cost, then, if you're going to use a new sporter barrel add another C$400. Scope mounts and rings will be anywhere from C$150+. Replacement bolt, which will likely need the handle replaced to clear the scope, unless you purchase European style high mounts (espensive) add another $200. Then you will need a trigger guard/magwell assembly as well which will cost $50 plus the cost of refinishing.

Just purchase another Zastava with all of this already done. It will be about the same as far as quality goes or better and half the price.

If you insist on persisting with this build, PM me. I think I have the receiver parts you need and a take off military stock.

Type VII, FN24 and Yugo actions
Action OAL: 8.500
Recvr screws, center to center: 7.620
Bolt body length: 6.115
Magazine length: 3.232

I have a Zastava 458 Win Mag. It is actually a standard length mauser. Bolt interchanges with standard FN and Brazil 1908 mausers. I actually have the bolt from a Parker Hale 7mm Rem Magnum in it now. Head spaces perfectly. I think the "Magnum" length mausers in the old days were for the big cigar-like cartridges, like 505 Gibbs, and such - as long as or longer than 375 H&H.

awesome thanks for the info, a big help. and i will PM you about the parts, i understand what you are saying about costs and wasted money, but there are a few things different about me, one i like old junk, two im a manual machinist who will do all the work my self while im already at work and 3 i dont plan on spending anywhere near that on this project.

my thoughts were the complete mauser missing the bolt was $85 shipped
169$ 9.3x62 barrel from tradeex so 220$ tax and ship in
and the bolt cost.

ill use sporter sights off old lee enfield barrels, the mag work and wood work i can do my self, straight or bent bolt ill use what i get and call her done once she feeds and shoots, then ill buy dies and brass and cast for it like all my other center fires i own

also i read those tapped holes are from factory and were possibly used for some type of charging system that bolted on, hard to find info, either way ill just use small screws in them

yeah tell me about it lol, i have to use a Woodleigh 480gr so i can load to the 91.5 OAL listed in the book (norma) so i dont have to touch the feed ramp (lower locking lug support as it runs 65k) i already have it feeding, now i just need to length the mag.

for the big ones ill start using P14 actions, the 500 jeffery im working on, the loaded round drops right into a p14 action just needs the feed rails opened up a bit for the width.

my plan is to build a whole range of big rifles on p14 and mauser actions. i have the 460 weatherby mauser, i ordered the reamer, barrel(50bmg gunsmith special canam) and bought a box of bullets for the 500 jeffery on a p14
so i still want to build a 416 rigby on a p14, and a 375hh on a mauser and a 9.3 on a mauser (as i can buy chambered, threaded barrels for the mauser action from tradeex in 375 and 9.3 so saves buying reamers for them)

Your rifle appears to be one made for Paraguay that was shipped to Turkey for the first world war . the two holes in the rear reciever bridge were for an extended clip charger , this was a Turkish modification. there is more info on this on line.
 
I have used a Yugo M48 bolt in a German made intermediate length action. The Yugo's use the "safety breech" style bolt face but they will work in the standard breech style receivers without issue. A M48 bolt is probably your best bet as other intermediate length bolts are hard to find. Turk 1903's (German made) are fairly common but it seems hard to find a bolt that isn't heavily worn from years of hard use by the Turk military.

Also, I would suspect your action has a small ring thread diameter with a longer shank than a standard M98 barrel. You will most likely have to modify that 9.3 barrel from Tradeex to fit.
 
Since you're planning on building rifles based on Mauser actions, I would highly recommend getting a copy of Jerry Kuhnhausen's The Mauser M91-98 Bolt Actions A Shop Manual. It contains valuable info on machining, strength, identification, measurements, etc. A must have for anyone working on Mauser actions in my opinion.
 
Turkish 1903 was originally in 7.65x54 and is an intermediate length action.

Could be a source for parts.

Nice, smooth actions. Many of the Turkish rifles came to North America after they were converted in the 1930s to handle the 7.92x57 (8mm Mauser) cartridge.
 
I have a spare intermediate length bolt (Kragujevac) with a spoon handle if you want to try it for sizing and handle clearance. Not sure I want to sell it though.

Like the two on the left.

Diopter, i may take you up on that offer as im getting conflicting measurments off the receiver. If you do want to sell it, i would love to buy it, if not id gladly pay shipping both ways to see if it fits. Thanks
Also those rifles are super nice. I love the look of them. They are exaclty what i want i rifle to look like.



Ok so measurments off receiver go as followed
Large ring- 1.410"
Small shank barrel .977"
Thread length .830"
Action OAL 8.750"
Bolt hole center to center 7.830"
Mag opening 3.270"
