Mamiya RB 67 back light leak

[icog]

<p><img src="../photo/8351965" alt="Test 1" />Hello all,</p>

<p> I've replaced the seals on all three of my backs and have discovered a leak on one that I was hoping someone could help me track down. I didn't find anything in my search that helped. </p>

<p> The back in question is I believe the oldest style Pro type with the swing out latch lock. It appears to be coming from the top about one inch from the left side of the frame. I've rechecked the seals to be sure nothing slipped and replaced the felt on the light trap. Is there anything I've missed? Since I only have a leak with this back I don't believe it's the body. Are the older type of film back shells prone to this?</p>

<p>Thanks for any help.</p>
