In the process of removing the chassis from the shell, a mystery part fell out--a little brass spacer. I cannot account for it in the repair manual, and am further distressed that it is only a single part. Notable is the certainty that I am not the first person in this camera, as I highly doubt the people at the Hasselblad factory tightened their whiskers in the interior screws. I've worked on EL's and ELM's before, but am having a hard time recalling this part. I've included 2 views of the part. BTW--I've also posted the question on the photonet site, but that is a terrible site to try to figure out. Not user-friendly. Please help identifying this part. Thank you.
