This rifle is definitely not a G33/40.

The G33/40 is a small ring Mauser action, but it has the appearance of a large ring action because of a step behind the receiver ring. That's one of the attractions to this action, in my opinion. Here's a photo:



The rifle is definitely on a small ring mauser action, just not a G33/40.

Sorry Pjaln, but you are wrong, the G33/40 is a small ring 98 action.



Correct.

As I mentioned above, a 98a...but...

Has anybody actually made a close comparison between a KAR 98a and a so-called transitional 98 small ring action?

For example, IIRC, all 98a/KAR actions had manufacturer's stampings on them. This one appears to have a clean receiver ring. From the pix it appears so to me, tho it may be scrubbed.

What are the salient differences between the 98a and transitional actions?

I mean, it is easiest for us to say "It isn't an Original Waffenfabrik Mauser", call it a guild gun or post-War conversion, etc, but according to Speed's Volume 1, and Vol III Archive {just yesterday I was given that one...EXCELLENT book!}, the more we know, the more we don't. Evidently many guns were made up on so-called transitional actions during a wide range of dates. These actions must have laid in storage for years at times and were used up catch-as-catch can.

This has been a very interesting gun to speculate about.

Rick R:

Can we pester you for some pictures of the bolt gas relief holes?

Also, how about a full list of the markings on the gun?

Thanks for posting!

Mr. Fiftyseven,

The only markings on the rifle are these:

Left


Right


bottom of the barrel


I notice that I posted the charge it was regulated with as "2,65" and it's actually 2,85.
The camera doesn't have 49 year old eyes.

It is common to hear of the 33/40 called a "smallring". The weakness of such terms is that they are generic and are both right and wrong. It IS a smallring of sorts, but it isn't in the sense of the smoothsided Mauser 94, 95, 96 and transitional models.

OK, so it lacks the BUGN proof, but per Speed, has the Crown/N indicating nitro proof years 33-39, export model. StmG indicates a full metal jacket bullet type. As for the serial number, doesn't it fit in the range and placement of transitional models?

Speed says parts were known to lay around for years before being assembled.

So...?

Rick R, can we bother you to shoot a couple pics of the bolt, specifically the gas vent holes?

Sorry, you did ask for an order of bolt pix to go with that.







Hope these help.

OK gents...

Large oval gas relief holes says regular 98 {technical term } to me.

Thanks Rick!

This has been a very interesting post. Hopefully the markings and bolt will be enough for somebody to give us a full description of what you have there!

The style of the powder charge/bullet type mark is what was used between 1892 and 1912. After 1912 it became

St.m.G.
-------
13 gr.

That is, bullet type over bullet weight, no mention anymore of powder at all. It's also not usual to see just crown-over-N (nitro proof), there should also be crown-over-U (final inspection) and crown-over-G (rifled barrel).

Looks like a very nice "mom-'n-pop shop" German sporter, and it appears to shoot really well - congrats!

Steve,

Thanks, I had read that the crown over N didn't go into effect till after the early 1930's but hadn't found the info about the change from load data to bullet weight.

I wonder if it took a while for the older gun builders to make the change from one style to the other.

If you gents are bored with the Mauser we can try to figure out where my SMLE has been.
