Snap-on Keychain Help

[Theronswanson]

This Keychain was my grandpa's. My dad kept it, after my grandpa passed away. I inherited it after my dad passed away a few weeks ago. My best guess is that it's from the mid 70's before grandpa retired from IHC. I don't care about value, as it's irreplaceable to me.

I have a money clip with the same casting. I got it from my neighbor who was a dealer in the 70s.

That logo was used 1953-1981. I started wrenching for a living in 80. the people that had that key chain
got them in the 70s.
