I bought this today on marketplace pretty cheap. It's a NOS, in the box Trail-Brite Chief Teardrop. It's friction drive and it has the same Chief emblem as Tuff-Bilt. The box says made in Hong Kong as was TB. Correct me if I am wrong, but wasn't Tuff-Bilt rebranded Dietz? I found a Trademark registration for Trail-Brite from 1976 and it looks like it expired in 1999. I don't have it in hand yet, but am curious as to what is stamped on the band. Hopefully a W3 date. If you know anything about it, any info is greatly appreciated.
