A couple of pics, maybe someone will recognize at least manufacturer.
Much appreciated.

Not at all, they belong to now obsolete, NLA Garland commercial oven controller.
It's the footprint that matters here not much else.
But now that you mentioned  it they do look like those in older infiniium scopes.
Hmm?

I did a search of images of Alps encoders, nothing came close.
I do think that they may be alps parts, but  I need to know at least partial model number or series.
