Browning .380 Model 10

Browning 9mm short mod 10

I just pick one up. and it seems to have a low serial no.
The no. is 22XXX I also believed ,until now, that these were made in .32 auto. The Belgian stamps are all there, but it doesn't have any markings of distributor. So it came into the country before 1968. The model ceased production in 1955, and it feels more like
a gun in my hand than ist Americanized Successor. Any ideas of worth @ 85% with some odd light scratches on the center of the slide
which also houses the safetey. Maybe it sat in a drawer for awhile,
and slid against the drawer bottom. Thanks for any input!!!
