Paul;

I am sending this info, but I don't think that it will be of much use. 
I have had this particular DR Summicron since 1960, new (along with my
M-3, new in 1957).  I purchased a M-6 last year, kept it for two days,
and returned it to the dealer.  I just like my M-3 a lot better.  

Anyway, here are the statistics on my DR:

SN:		1749743
Marking:	1:2/50
Use eyes?	yes
type:		early
bodies:		obviously works on my M-3, seemed to work on the M-6
force:		no excessive force required on either body
repro scales:	no
scale:		both english and metric
distance:	scale in english ends at 21", metric ends at .5 meters,
		actually mechanically rotates to what I would guess to 		be 20".
