Thanks for the additional info everyone. I haven't taken out the BB yet (or done much of anything short of a quick wipe down) so can't comment on the ports... this will definitely be a slow project, but will be sure to post pics as things get cleaned up over time!

redxj, thanks a ton for your offer, I've already been referred to someone in the area who is familiar with these frames but will definitely PM if I need some outside assistance.
