I saw a square taper BB today that looked to have a different taper, I tried it in some cranks and the taper was different, it still wobbled when it was pushed fully into the crank.

Looking on Sheldon Browns site JIS and ISO both were 2 degree.
So what could this have been?

Didn't the BB units on the original Viscount Aerospace models have an odd quirk like that? Or was that the crank arm tapers?

Possibly one of the above then!
I wish I'd had a proper look at it now!
