[Leica] HELP!!!! - M3 disaster! Advice sought

[pdzwig at summaventures.com (Peter Dzwig)]

All,

travelling in France. I knocked my M3 off my bedside table and it fell
on to a floor of "tomette" tiles, landing square on its top plate.
Result is that I can only see the centre focussing rectangle and the
framelines.I presume that this means that I have somehow managed to
shake the viewfinder loose in some way.

(i) anyone got any smart ideas to fix it in the short term;

(ii) Obviously it needs to be properly fixed when I get back in two or
three weeks. Anyone got the name and address of a good M3 repairer in
the UK? I know it could go back to Leica, but I suspect they will charge
and arm and a leg and take forever, and as it non-current technology I
bet they won't be too keen.

Thanks

Peter

PS to make matters worse the IIIf is away for a CLA. I had thought about
Classic Camera and Red Dot in London but personal recommendations count
for a lot :-)
