The story of the train wreck.
I recently had bought a set of used VAR taps that were British threaded.
Turns out they weren't British, turns out they were Swiss! Unfortunately, I didn't know that and so initially, I just assumed the BB was not British. After all, the tool couldn't be wrong.
I went to see a friend who had several sets of taps. I then threaded on a set of taps that fit. He said they were french.
Identification solved.
Wrong identification.
I went home and posted this thread. My friend emailed and said something was wrong because he had realized I had used his British taps!
Recheck and we discovered my taps were Swiss!!!
I have never seen a Swiss BB in my life. I traded him for a spare set of British taps.
Lesson learned.
