The erma looks good to me. Very early 27 code right when they were changing from s/27.

Don't know if you plan to shoot it, so It may not matter to you, but it looks like the recoil bolt has "setback" in the stock. It can be repaired, had the same issue with my RC 27 1938, but I would take apart and check for cracked wood behind the recoil bolt and repair it if indeed it needs it before shooting.
