Leica Beam Splitting Mirrors etc

[Tancred]

Hi, I am currently refurb'ing a 1932 Leica II screw mount (aka Leica D)

Can anyone advise of the proper dimensions and best Transmission/Reflect ratio for beam splitting mirror for a Leica II (Leica D). I heard that T/R was 30:70 for pre 1939 and 50:50 post? Which is best for contrast?

I think there is a size difference pre and post 1939 and a difference with series III camera as well? Although I suspect its something around 8 x 10mm

Any thoughts on good source would be helpful. I have not made any progress in reaching SH camera as per other posts in this thread. Maybe I looking in wrong place

Am also looking to replace RF port glasses any advice on dimensions, spec, source gratefully received.

Many Thanks for any help

Geoff

Agreed, I have one of his in a IIIg body and contrast is very good.

Nobbysparrow is the best! Last time I ordered from him was more than 10 years ago, he remembered, and threw in a free mirror. His books and videos on youtube are also great.

Make that four, he is good for other bits and bobs too.

I have used his mirrors on original III as well as IIc/IIIc models. The mounting is a little different in the older ones as originally the mirrors were not stuck but held in place by a frame and a leaf spring, this is why thickness is a slight issue. I have just added a thin shim but they can probably just be stuck. Your II will probably be similar.

Does your II have the 1.5x “focussing” eyepiece or the standard 1x? As far as I can tell there is no difference in the actual RF/mirror part so it shouldn’t change anything.
