Colonial? Celluloid? Help!

[Bigduck1]

Hi all!
I have a cool looking little pocket knife that I’ve been holding on to for a few years and trying to identify it. It has a neat Black, reddish burgundish shiny pattern handle slabs that I think could be celluloid. The knife is stamped U.S.A. Only on the secondary blade. No other markings that I see. So, 3 questions for Ya:
1. Who made it?
2. Is the handle Celluloid or some other composite?
3. Approx. Age?

Photos attached…
Many Thanks for any help!

That's almost certainly a Colonial. They made alot of advertising knives with tipped bolsters like that. I'd have to guess that's celluloid. With it only stamped usa I'd say it's an earlier one from them.

Colonial.
Celluloid.
1940s-ish.

Thanks again for the help! Good news is, I’m getting slightly better at figuring things out but it takes me a looooooonnnnnnggggg time and I still don’t trust myself much. That’s why I like to go to the Smart Folks

From your pictures it doesn't look like it's bombed yet, but I would be careful to store it away from your other knives.
