Oops - should have been 48-28.
Went back and bought the crankset tonight while waiting for an emergency wheel true (after jumping the pannier off the rack and into the rear wheel on a parking lot entrance).
The crank arms are well worn and will need some polish and light sanding to get a lot of the scratches/scuffs out.
Here are the rings - called Bio Strong. The cranks can be run as a triple or double with a 110/74 bcd. There was no middle ring but the 48 and 28 Bio Strong rings are in decent shape. Gotta be from the 80's.
