Nice looking rifle,,love the M/S's

Wondering how the 270 Winchester (length cartridge) was fit into a 1910 MS action/magazine.
Maybe it's not a 270'Winchester'. Just a .270 on a '56mm case'.

The 1924 Model M/S was offered in 270 Winchester I believe. The rifle may be one of these. Or a highly modified 1910 perhaps??
The rotary mag from a 1924 won't interchange with a Mod 1910.
The Model 1924 was made until 1940

Also the post war 1950 and 1952 which both still had the pre-war features were made on the Mod 1924 long action and would accept a 270Win/30-06 length cartridge.

Seller notes ..'Niedner rifle corp ,MI faintly on side of barrel serial number on underside of stock,import marks?'
