So yea, a legitimate TA crankset, and the only reason I bought the bike.
I always appreciate the vast knowledge running through BF. And what you guys shared, I did not know other than Lamberts and Viscounts could have press fit bottom brackets. But the extra details and information just given, is not only interesting, but confirms for me once again that the world of C&V bikes is a black hole of oddities!
Well, Lambert/Viscount is among the oddest of the odd.
AFAIK, all the lugless Lambert/Viscount frames came with press-fit cartridge bottom brackets. If the bottom bracket on yours is Italian thread, chances are it was an aftermarket modification. Reaming and tapping the lugless frames to use an Italian thread bottom bracket was a relatively common fix when the original cartridge bearings failed.
