Where were these pedals used?

I picked up some parts yesterday along with these pedals. I have seen them on various bikes ove the years. These do not have any markings at all.

Were they just a universal part from back in the day?

Yeah, they look like just universal Wald or Union pedals. Use them on anything!

Judging from the lack of wear probably an exercise bike... :lol:
