If the bottom bracket is Sugino, it should say so on the cups, as well as giving you the thread type:



"1.37" x 24T" is British/English thread -- this is the most common. Older Peugeots had French thread bottom brackets (35 x 1.0) but IIRC by 1982 they had changed over to British.

As noted above, the BB is likely set up for a double chainring. For SS/FG you will want to use a ring mounted on the inner plateau of a double crank to get the proper chainline. If you use a track crank designed for a single chainring, you will need to replace the BB spindle with a shorter one to move the ring inboard for proper chainline.
