Difficult to make an estimate, but I'd bet something between $600 and 1100

after some more research, and talked to some old school camera guys here locally, they said it should be a T2 mount. Not sure where this leads.. |

T2 (that's a more modern thing) would mean it can be adapted by cheap adapters to every SLR.
But I doubt that it is T2. T2 has a finer thread.
Anyway, there should be a camera shop somewhere with an old praktica or pentax to try if it is M42....

It's M42 when it fits into your EOS Adapter. As said T2 is also 42mm but has a finer thread and won't fit into your adapter.
so
+1 for altered lens, because theres no depth of field scale. I wonder who made this modification. I would say it's about 600-800€ worth if the glas is without haze and focus and aperture are not stiff.

I think this mystery will never be solved.
The modification, T2 or M42, doesn't look like any aftermarket work. The metals on the top and bottom are similar in color and quality, also the age seems to match. There's no welding marks anywhere so the whole bottom must have been swapped.
I think there's more to it than just a hollow bottom as the elements seems to be sliding on rails on the inner size. this would make it extremely hard to mill out a bottom just for this.
Another old lens expert suggest it might have been a custom order lens for military use or a limited run for some gov't work, etc. But no way to tell, and no way to proof.
