Hi chaps.

I recently came across this Crosman 137, in .177 cal. It shoots very well, is accurate and still has plenty of power. I'm used to Webley's and old spring powered pistols, so this is quite a fun new experience to shoot a classic vintage pistol with zero recoil.

Ive read somewhere that it isn't possible to date these pistols, but I'm not sure if that is correct. There is a serial number stamped into the breech hatch/slide. It is 71448.

Would anyone know what this number indicates?

Best regards to all,

Will
