Hi.
The numbers are:
receiver stamp 1938, s/243.
eagle stamps on barrel and receiver 280 underneath,
ser # 3092 with a lower case cursive" a" underneath,
extractor and collar stamped 89 as viewed from left side,
bolt handle 8589 with small "f" underneath,
bolt sleeve and safety lever 1771.

It'll take fome cleaning up to read the number on the bottom of the bolt handle and a magnifying glass to see the number on the rear of the extractor.

I assum the "1938" is the year and the S/243 is Mauser Berlin?

Not sure abou the other markkings.
