Well I hope these are original bakelite grips, how do they look to you guys? Guess it's time to google bakelite.
Edit: Well I'm fairly certain they are original, the inside surfaces don't look like modern plastic.
And when rub my thumb against the inside to warm the surface, I do notice a musty smell.
The material inside looks like what was used for old pot handles or distributor rotors.
Hopefully these pictures show enough detail.
I don't see any markings inside but the eyes don't focus up close anymore!
Thanks!
Bob
