I've been looking around for a used Leica M7 and want one with the MP view finder mods in it and if possible the optical DX reader.
B&H had a possible one with the 0.85 rangefinder and a 9+ grading. I emailed their Used Sales group with the questions and the serial number where the MP mod was started on the M7.
I expected not to hear any thing back today. In less than an hour I had all the information I had requested and the serial number of the camera to send to Leica if I wished to see if had been retroactively moded. But alas no joy, serial number before the mod and the old DX reader.
Back looking but I found
B&H outstanding in their handling this rather complicated request.
Still waiting to hear from Leica regarding any warranty work.
