Mauricio, there's every chance that early Aldis Anastigmat could be a very fine lens indeed. I'd be interested to see what it can do wide open.
This little gem apparently spent some ten years living in a garden shed in Wales, and it took a LOT of work to get going again - lens, shutter, rewind, rangefinder, all needed work.
The appeal is that it is sooo small for a 35mm cam, and in the end it was (sometimes) worth it.
