It's a Russian-made Model TT-33 Tokarev, in original (as-issued) condition.
Many imported Tokarevs have had a safety lever added to them, to suit US laws. Yours doesn't have that.
The two Russian-language letters (approximate values "ee" and "dj") which precede the numbers may be part of the serial number.
Its manufacture date, 1941, indicates that it was made early in WW2. I believe that the star indicates military issue, but I don't know for certain.
The grips look original. Don't try to remove them, because the plastic may be quite fragile. (They unhook from inside of the grip.)
There seem to be no added German markings, so it wasn't captured by the Nazis.
It may have been used in both WW2 and in some subsequent conflict. But how would one know?
Value ranges from about $650.00, down to $100.00.
Yours seems to be in pretty good condition, and it's historically interesting, so that might keep its price on the high side.
