K98k bolt stop question

Question for the detail buffs... ;)

At some point (I assume in late ww2, but I suppose it cold be a post-war phenomenon...?), Mauser 98 bolt stops ceased using a one-piece bolt stop spring arrangement and switched to a 2 piece bolt stop spring arrangement where a stamped sheet steel spring was retained in the bolt stop body to tension the ejector, while the larger spring was only to tension the body into the closed position.

anyone know when this design change came along? Who employed it?

I typically see this later style on un-marked rougher-finish bolt stops, and they seem FAR less common than the one-piece spring type. I've also PERSONALLY not seen them on the type with the prism-shaped ledge for the retainer screw. Every one I have seen had a more typical round ledge for the screw like MO tended to use, even late in the war.

Thoughts?
 
Well Claven I can honestly say I've never seen that or at least never noticed a spring arrangement like you described. Do you have pics of the two types? I sort of looked through my k98k's and other Mauser 98's but didn't notice anything out of the ordinary. Can you tell without taking the bolt stop/ejector assy off?

No, you can't tell without disassembling the spring off the bolt stop body.

I've partially answered my question though, I was tearing down a matching bnz43 action (no bbl or stock) to prep it for claw mounts and decided to take apart the bolt stop. It is of the later-style steyr pattern with a prism-shaped ledge, and it has a two-piece spring. So I was wrong, prism-type ledges can also be 2-piece. Also, it proves the change is wartime because the 2-part spring is WaA77 marked and matches a 1943 action.

I'll try to take a pic later to demonstrate what I mean by 2-piece, but here is a one-piece spring:

I have seen those 2 piece assemblies before. My 1939 "243" model had a two piece assembly, with serial numbers and Wa26 proofs stamped all over the rifle, even on the 2 springs in the ejector box. I later found a set of springs marked Wa77 (see picture). I always thought they were only used on pre- or early war models.

Somene be at me to it, but this two-piece is from a matching bnz43 and has a waa77 on the larger spring.

 
That's very interesting. I've had the springs out on a few M98's but never any German k98k's and never noticed that before.

Always something to learn.:thumbsup:
 
The more I look at it, I think the springs are interchangeable, or put another way, the housings are universal. Still curious when the change was brought in and if there's a pattern or not (?). The 2 piece seems easier to maintain and less likely to break IMHO. Probably an improvement.
 
I have one 655 box missing the spring, anyone know where I can get a replacement.
Btw, just curious, how to secure the small spring on to the large spring cover?
Thanks! Regards Kelly

Go check out The Historical Parts & Militaria Company. He has what you want, but I think that you have to get the whole bolt stop box assembly, doesn`t cost much. PM me if you need more info on the web site.
