Thanks Dons,

We are getting together all the components to build a replica of a Mauser Type A in 9.3x62. Like Osa Johnson's rifle that
Bob Faucett has and graciously posted pics of here.

Lothar Walther has a barrel contour #5130 that is supposed to be an exact copy of a Mauser Type A in 404 Jeffery.

They list a muzzle diameter of .625" on 26" long barrel.

Contour #5130: Mauser Type E Sporter (for type A rifles)

ØD1 = 0.625"
ØD2 = 0.800"
ØD3 = 0.865"
ØD4 = 0.923"
ØD5 = 1.200"
L1 = 2.00"
L2 = 2.79"
L3 = 3.79"
L4 = 6.49"
L5 = 26" LW contour # 5130

I couldn't get the barrel drawing to past so here's the link:

LW contour # 5130

I have been going back and forth a bit between a 10.75x68 built on a 1909 Argentine or a 404 Jeffery on a GMA Standard Magnum Single Square Bridge Action, to stay as close to true to the Mauser Type A. I guess the 404 Jeffery would be a 404 Eley according to the 1930 Mauser catalog reprint I have.

So, I guess I need some help and guidance on the proper barrel contour for a Type A Mauser in 9.3x62 and 404 Jeffery.

Any help would much appreciated!

We want to build them as period correct as possible.

Cheers, Allen

PS, If I go with the 404 Jeffery on GMA action (the most likely option) it will have a flag safety, mil trigger and bolt handle like a Type A, not the GMA bolt handle.
