Tonight on unsolved mysteries…

[Chadillac]

I need some help identifying this frame. It came with 28” metal clad wood rims laced to new departure hubs, model C coaster break. Skip tooth. Frame and fork are too narrow for balloon tires. Thank you in advance for any input.

What do you see that tells you it’s a Schwinn?

I am also thinking Shelby.

I was leaning Shelby myself. Only my second moto type frame so working on trying to tell them apart. All so similar in those days.

Relatively large (looking?) ~1” truss tube; and maybe the forged fork crown?

Badge holes look to be 2 9/16”. Yes, I completely disassembled the bike before the restoration, but I can’t remember what markings were on it.

G.W. Grady New England Motobike: Who built this frame? | Antique Bicycles Pre-1933

As posted in this week’s show-and-tell, I just bought this teens/twenties period "New England" badged bike. Please help me out with identification of the frame builder. G.W. Grady was known to be both a bicycle jobber and a manufacturer as well. Any thoughts?
