Speaking of Frankenlenses, I've just adapted a Taronar 50mm 1.8, it's a mid 1960's Rangefinder lens. What's very odd is that it seems to have two apertures?

The one closest to the front element has an aggressive 5 point star shape, while the 'rear' blades make for a square shape. Does anyone know whats going on with this thing?

A guess, but that sounds like one is the aperture iris and the other (the square one) is the shutter.

I am still free lensing within an adapter socket, and it seems quite sharp but has very corny star bokeh in my first session with it. I can send a pic if necessary.

Some USSR lenses did that too. The bokeh will look like the aperture.
