Looks just like the Topline cranks that I bought new on my Fat Chance at the end of 1993 which I still have & ride.
There are reports of splitting on these cranks at either the pedal eye or the BB axle end. I heard somewhere they really are for lightweight weight weenies ( 150 lb. rider was one number tossed about). I am still under that number & picked up a spare pair on the Bay about a decade ago. They sure are pretty.
