I'm not in the German glasses, but to me, it looks like homemade mount conversion.

Okok, I realize the housing looks strange and possible homemade or whatnot.
But is it just me, or does it seem that the front of the lens and the filter ring are different and shaped differently than a regular trioplans?
Isn't the designation on trioplans usually on the barrel/outside filter?
Dead on, it looks more like a primoplan.
Either way, very interesting.
