Thrift Store Find Rodenstock - Rotelar 1:4 f=75mm Lens Question

[iKokomo]

I just found this lens at a Thrift Store and I was wondering if anyone knows anything about it. What is the history behind this lens or what camera does it goes to?

Seems like a better than average vintage lens so I got it for $7 USD.

I'm guessing an enlarger lens. maybe.

Enlarger lenses wouldn't have an aperture actuation mechanism on the mount end of the lens.

A quick Google search found this:

Rodenstock Rotelar coverage anyone ?
