Bought a lens last year off fleabay for $5. I had no knowledge of it other than it was cheap and "looked" clean. It was from an estate sale.
Anyway, it's a Voightlander Braunschweig Tele-Dynar f/6.3 29cm. Has a plate on it with Burke & James. Remarkably well cared for, spotless glass and body in shutter.
I have a few Heliars, but I have yet to take this out for a spin. Anyone have any 1st hand experience with it?
