Hello,
I found an original manual, dating 1964, on the PDP-5 computer (https://en.wikipedia.org/wiki/PDP-5), and I also have the front-panel.

Do you guys want these things?

We're interested in emulating everything. We'd love to have scans, schematics, photos, anything.

The PDP-5 is a 12 bit DEC machine, almost the same as a PDP-8

Bob Rosenbloom (dvq.com) has one http://dvq.com/oldcomp/dec/pdp5.html
he may be interested in your panel for repair parts.
The manual et al are on bitsavers http://bitsavers.org/pdf/dec/pdp5

Wouldn't it be good to scan or photograph the front panel before it is given away? Artwork files spring to mind.
