A mystery pre-war 30-06 JP Sauer came home today

I didn't know a lot about this one other than I like the way it looked.

I though it had a miss-matched Bolt, but found that number on the Action also.

I assume this is between the Wars, but not sure of year of mfg.

Here are the specs..

21" Octagon to Round Barrel, Full Matt Rib to Ramp Front Site w/ Silver Bead
Lyman 35 Rear Site - (orig rear site on rib is milled down)
7 lb 6 oz
14" LOP
Type B Floor Plate Lever
Double-Set Triggers
Barrel Rib marked "Mod Mauser: J.P. Sauer & Son"
Barrel side marked "30 U.S.G.1906"
Barrel shank marked "Fluid Steel Krupp Essen"
Barrel marked "Crown N STMG / 10G"
Action and Barrel marked "182644"
Action marked "44580"
All Bolt parts marked "80"
blank brass escutcheon on bottom of stock
Braided Sling

as always comments and opinions are welcome ....
UPDATE ... I FOUND AN IDENTICAL RIFLE HERE - SAME FRONT SITE AND LYMAN 35 SITE - https://www.gunsinternational.com/g...02267632&usource=lc&lctid=509172
