BB for crank?

I just scored a used Suginio 65 track crank ($25!) for my new Soma track frame, and the next logical thing to get would be a BB. Anyone know the size for this BB offhand? Its not on Sheldon's list, unfortunatly.
Thanks!

I use a shimano UN-73 107mm with my Sugino 75. I wouldn't think the chainline would be that different between the two cranks.

Not all asian stuff uses JIS taper. Track cranks like the sugino are typically ISO,and suntour, also made superbe stuff in iso. The ISO reference was to the sugino 75...duno what the 65 uses. Try sliding in on a known jis taper and if it only goes about half way or less, it's iso.
