Mauser es340b/es350b transition to dsm34/36 features

[oldwing]

This screen shot shows some discussion of the “B” series change from the early low extractor/rectangular port to the high extractor/oval port in a somewhat lengthly thread. No point in adding to that post so I’ll start a new one. I just got this es350b that shows the late features, serial number 151147, typical features, stock has no serial number..

Oldwing,
there is a unusual number engraved on the top of the receiver. I cannot read it.

 

[oldwing]

Eurydice, 1926 is stamped on it ( certainly not the year of manufacture! ). and some other marks that I can’t make out. Also this is stamped on the stock.

 

[oldwing]

KOMP, possibly Königswinter?

 

[oldwing]

It would be interesting( at least to me) at what serial number the transition occurred. Was there any overlap in the serial numbers? If this has been determined I have missed finding the info.

I am glad I didn't drive the price up any further for you, though I would have preferred you let me have it!

I don't know that we have determined exactly when the transition occurred, and likely there is no hard transition line. There is a jumbled mix of features and if I had to guess at this point, there is likely a 10k or more range where the changes occurred.

I have ES 350B 151034, which I was curious to compare to this rifle, and see if the features are the same. Does it have all later features? Can you post pictures of the bolt face, extractor, and ejector cut? If my memory serves 151034's stock is also not numbered, though I have not seen stock numbers consistently.

 

[oldwing]

Falgrunt, here should be some photos of the bolt. I was a little pleasantly surprised that all numbers match, bolt and sight numbers.

Deleted double post

the 4th rifle from the bottom is the grooved barrel es340b from the early 140,000 group , all seemingly to have the early bolt and rectangular port. Another can of worms… the bottom 3 rifles all are es350Bs with late features. I’ll remove the stocks and check for numbers but it does seem stocks might or might not be numbered.

 

[oldwing]

Es350B number 162764 stock is numbered

Es350B number180911 stock is numbered.

 

[eurydice]

Had to think about the infos. No idea concerning the stock marking, I just found that Wilhelm Marx was the justice minister in Germany in 1926...
Concerning the rifle itself, it presents DSM36 features except the bolt face that is un-recessed with a long bolt ejector groove.

I just checked s/n 151457 (pictures below), it presents the same features as your. As you can see on the pics, the firing pin is v shape (correct for DSM36, normally rounded in un-recessed bolts). The rear sight's positions on the barrel are 0-9 numbered.

Thanks for the additional photo's, I'll add that to its file.

Your middle rifle in your group picture, can you take some more pictures of it and provide some more information? Primarily interested in serial and features. I have one just like it and wondered if they did a batch with those sights, or if it was merely a special order sight.

 

[oldwing]

Falgrunt, unfortunately the sight happens to be a replacement I found many years ago to replace a missing sight on the es350b.

 

[oldwing]

I’d assume the screw in the sight plate was added by a previous owner, although the plate lock is fully functional.

These mikrometerviser were available before the B serie.
According to Jon Speed, the "Schraubvisier" was available starting 1927.

I am new to this forum as of today and ran across this post. Just acquired a Es350B yesterday and am looking for some info. Basic details are; Serial No. 1933xx, Walnut checkered stock w/Mauser cartouche & butt plate. Trigger guard is checkered as well. Has several hallmarks, "B" over crown & "U" over crown and other that I can't make out as of yet. Mauser type bolt(Type 3 maybe) with same hallmarks on base & 5273. Original rear sight replaced as it wears a Unertal 1 1/4" target scope now. Any info about this is greatly appreciated.

Thanks,
Doc

Doc, from material from Jon Speed’s book I would guess your rifle was made around 1938 or 39. The es350b was the top of the line for production singleshots. The missing rear sight usually is hard to find and very expensive but searching might turn up one. Have you had a chance to shoot it? I’ve been trying to come up with a way to put a Unertl on one of my es350s without drilling but not satisfied with my adapting so far.

 

[usmcdoc67]

Been doing some research and found a post with a serial number 1999xx that was dated to 1939. Not knowing yearly production numbers, would guess mine likely was made in 1937/38. Haven't had a chance to shoot yet, but really looking forward to doing so. Mine looks to have a two weaver style bases attached for the Unertl scope, which is a 14x. One just aft of the ejection port and one at the number 4 on the barrel scale. Would assume(?) that they are tapped for mounting and the scope is attached thereto. However, not going to remove the scope to find out. At any rate, it's a beautiful old gun with most bluing in tact. Stock is outstanding tiger strip with original finish. Bore is bright with strong rifling.
