ID help for my friend

[Lonestar]

My buddy just got this going, it was is Grandfather's bike. He said his Mom painted it multiple times over the years. He wishes he knew what it was & I am trying to help a Brotha out...

This is the only pic for now, I can try to get more from him if needed...

Thanks for the help!

FAQ: What Is Hydrogen Furnace Brazing?

Hydrogen furnace brazing is a technique where brazing is accomplished in a pure hydrogen atmosphere without flux. This process is used for many alloys.

You got me wondering what "hydrogen brazed" meant, and according to the internet it's a "brazing process that uses the cleaning (reducing) properties of high purity hydrogen to improve the flow characteristics of the braze alloy." 🤔 That's a new one on me!

I was clueless on all of that jargon! I thought he was messin' w/me! But I appreciate any feedback...Thanks @Oilit !!
