Hello all,
I'm trying to learn the terminology for the end of the mainspring that attaches to the barrel. I have already figured out 'T', (thanks to the Tascione videos), but 'D.B.', 'M.B.', 'T-Brace', 'T-Hook' and 'Tongue' continue to elude me.
I haven't been able to figure out the right phrase to enter into the Search function, so I thought I'd try here. Can anyone point me to a chart or something? Thanks in advance.

Michael,
Check your e-mail. I sent you a picture of the different ends.

Brian: Thanks very much for the picture.
Chris: Thanks to you also.
