OK, I had a change of heart and kept the Triumph to tinker around with.
- Just completed my first attempt at cottered crank removal... yay!

It has an interesting mix of components, I wonder what's original:

Huret mechs, Sturmey Archer hubs (red-logo Raleigh nuts on rear), Raleigh cranks, sprung Schwinn saddle, Regina Extra Oro freewheel (13-22), and Weinmann brake shoes on side-pull calipers that simply say 'Made in England'.
The BB was interesting: the spindle has a Raleigh logo, but there was a plastic DuraAce sleeve in the shell - didn't expect to find that!

I'm still trying to determine the age of the bike. I found one serial # on a dropout. I think it translates to 1966, but I could be wrong. It wasn't really the rattling rustbucket I originally thought, just very dirty and neglected.
