However I question just how old it is or if it's really a 1930s Winchester knife.
Please review these pictures & chime in with your ideas.
It is a thin jack knife with tip bolsters.
Brass liners with the center liner cutout in the well.
It feels like an old prewar knife to me but there is no pattern number & the red scales seem a bit off.
Thanks in advance for schooling I am about to receive.
