schwinn typhoon crankset / chain ring

I picked up this older early 1960s Typhoon frameset cheap. I had piles of parts in my parts bin.

The original chainring is the one with the circles......46t.

I have some bits of sram pc-1 chain which seem to fit. This is a single speed chain. I have bits of sram 890 and 951 (8 sp and 9sp)...
