I believe it to be a very early 1923 model by the low serial number.
It has a highly coveted magazine! (search for them on ebay-if you find one,expect to pay $65-$100;or more!)
Pretty good condition for being 93 years old.
Wood is good,metal has some bluing loss in spots,but no rust or pitting.
Stamped 22 long rifle,but I consistently use Colibri 22 short subsonic in it.
Shoots great,I just put 5 rounds through it in my back yard 10 minutes ago.
$150 or trade for-
AK mags,prefer steel but any considered.
1911 holster (traditional style in leather or nylon,no molded plastic)
