Here's my modest contribution: a Challenger 1260 made in Canada.
A local listing had a 1/2-Proto 5449 and a 3/8-Challenger together for $10. It was a poor quality shot, but I wanted a couple of user ratchets for my carry bag.
Got them both home and each had been engraved, no big deal, but a wee bit disappointing. Neither worked well. Disassembly showed why, both had ancient grease that had turned to wax. Disassembled and flushed all clean.
Also had a go with my scotchbrite wheel on the engravings. Good progress on the Proto. The Challenger was deep, but it did make a difference.
Cleaned out both, added judicious amounts of Super Lube/(PTFE) and now both work beautifully. It's nice ratchet, compact, light, but sturdy.
