p&c transitional from plom or proto

[tyheuser]

Thats crazy about the grind off tools my dad has a 3/4 drive socket set thats all super old looking mostly plomb p&c and snap on and has a couple of sockets over 2 inch that are only stamped with the size and USA and the brand is grinded off them Ive always wondered why you learn something new everyday. He just gave me a 3/4 drive snap on ratchet and breaker bar that date to 1941 I feel guilty about it but im trading them in to my snap on guy for the new ones with beefier handle and he also gave me 2 p&c 3/4 extensions that look brand new! I love old usa tools
