T-mar, I believe this predated (1960) SL, PS, etc. Did the tubing preferences for track vs road change over time?
It does help explain why it’s upside down. The frame builder would have flipped it to adjust the butted sections. I have only ever seen tubing stamps on steerer tubes, so I learned something new.
Yes, RHM, I meant the vice. Apparently my squat rack was on my mind. 🤣
I’ll spin by the tool shop and see if I want to drop the coin. I may cheap out and try the c-clamp. It sounds like the bikesmith press is less than ideal.
I stripped a bit of paint off the lugs and the chrome looks perfect underneath. I can’t believe they painted over it.
