[Leica] imarect prism placement

[smotter at earthlink.net (Stephen Motter)]

Hello all, this is my first post to the group...
I have an imarect which has taken a fall, and now one of the prism has 
come loose. I've gotten inside (very nicely made in there!), I've 
unscrewed the prism train, cleaned everything etc. but I have this one 
lonely loose prism and don't know exactly where to put it. I assume it 
needs to be glued somewhere, despite the fact that the other prisms are 
held in place by metal braces. I've placed it in different locales, 
close to the eyepiece, but cannot get a view. Can anyone tell me, for 
instance, where the long side of the prism goes in relation to the 
eyepiece? Or, perhaps you have a shot of the inside of the finder to 
share? Thanks so much for any help!
