I tagged him in my post above.

He seems to not have posted for some time so I do hope he’s OK

You have posted in the proper forum. Change (if possible) the header name of thread or start a new thread with the bike brand in the header and need help IDing model & year.

Not sure it there is a dedicated Butler thread; but it would more than likely be in this forum.

Thanks Jesper,
Makes more sense

It's strange that 501 isn't better thought of. Every 501 bike I've had has been really good and I've regretted selling them.

Seamed tubing was looked down upon as inferior to drawn tubes before tange perfected the process (or at least the marketing attached to it).
"A cheaper tube set was created by Tange in the 80s: Infinity -- designed as a good quality but low-cost set for lower-priced bicycles. It was a seamed tubing, which meant that it started out as flat stock. It could be rolled out with different thicknesses along its length, then formed around a mandrel and welded into a tube. Additional working made the welded seam invisible. Many people would be turned off by the thought of seamed tubing, but in reality, there was not likely a big difference in strength. And the manufacturing method used meant that the butting could be customized without adding complexity or cost."
