Recently acquired a Topcon Super DM at a good price due to a couple of issues:
1. Dead meter
2. Cracked prism
The first fault turned out to be dirty switch contacts - which responded to a strip and clean. I bought an RE Super/Super D prism head on fleabay thinking I would swap the prisms over, but this doesn't quite work - the RE super prism is a bit shallower and doesn't have the cut out in the silverining that allows the 'judas window' (by which you can see the lens aperture setting) to work. I tried removing a bit of silvering from the RE super prism, but whilst I can now see the aperture it appears very high up in the viewfinder. This is obviously why the original Super DM prism is a bit taller.
So - here's the really long shot - anyone have a Super DM prism or prism head they'd be willing to sell to me?
