Wedgie,
I'm not sure if you could use this as a reference based on the Mauser action itself, but if blown up large enough you may be able to scale up from there?
Type B
Type A
Mauser PreWar?
Also added info from Lothar-Walther Barrels
Mauser types Page 17
Hopefully Lancaster or Kudae might be able to assist in this regard as to which 'profile' matches & then go from there
Fingers crossed for you matey
Certainly a worthy project!
Thanks for the links - the first one is what I’m after I think. Scaling from a photo would be a bit tricky To do accurately, especially as the photos pixelate quickly when blown up. Might be a good one to fall back on though...
The LW profiles on page 17 are good, however the ones that interest me most are the type E - regular and lightweight. But pretty sure these are type A profiles
Quote:thanks a lot for the offer - but I’m pretty sure he’s referring to type A (which was Oberndorf’s English style - Type B was their “continental”). If I can’t find a Type B profile I might take you up on that though! It’s slightly odd that there seems to be a lot more info and options out there for Type A rifles than Type B - although just going on auction and sale numbers Type B seem the more common rifle nowadays...
In page 124 of Jon Speed's "Original Oberndorf Sporting Rifles" there is a factory drawing of the Type E (English) barrel profile used on rifles made up in calibers from .250" to .350". It's pretty dim and I'm not sure it would scan legibly, but I am willing to give it a try if you will let me have your email address.
Jon Speed says 6.5" to .404" in the text, but the label on the drawing clearly says ".250-.350 u. 6.5-9" The barrel length is given as 600 mm (23.6").
