Thomas, to stay on topic I really appreciated the Mercedes technical Info. Changing the rotors on my 300E is going to be a bit simpler.
As for the camera, I suspected an M2R but wasn't sure. I have an M3, SL and SL/2. I stupidly traded my M2 for a Nikon Ft a long time ago but went to Leicaflexes after a series of Nikon F's. My M3 cost me $288 in 1966 and it's now worth many times that.
I'm also enjoying your galleries Some good stuff in there.
