It’s my non-expert understanding that it says Chicago on the badge if built there and says Quality if not. That’s what I see with my Schwinns anyway.

I was able to find an NOS set of decals on eBay for my High Sierra, so maybe you’ll have some luck there. I like to make my own decals for repaints, but the tricky/impossible part is printing light colors on clear decal stock to go on dark paint jobs. I have generally compromised in that case by printing black decals or black outlined letters through which the color of the frame paint shows.

But I now have a Cricut, so (although I haven’t done it yet) I believe I can print decals of any color on white vinyl stock and then precision cut them with the Cricut to transfer onto the bike. In that way, I believe I could recreate the originals, or create a mask to paint the original decal onto the frame. Oldshovel used to do this a lot in his earlier YouTube videos. So if you have or know someone with a Cricut, you could experiment with that. My preference is to ride a bike with a nice paint job and riffs on the original graphics than one where I’m not happy with the condition of the original paint and graphics. But I know that keeping things original means more to other people, and I have a couple of bikes where I’ve gone that way myself.
