well thats a bit of a tricky one but id imagine its worth more than most given it has german stamps on it
and its in decent overall condition definitely seen some use
id say about 700 dollars or so
C series in serial number range puts it at about 1943
and good luck finding ammo theres only 1 manufacturer im aware of that makes 32 french longue and its been out of stock since 2019 on top of that if you manage to find any original ammo they are all basically duds with bad primers
