This isn't quite "electronic" restoration but it does deal with the chassis so...
I took a shot at reproducing the model # stamp that was on the back of the chassis...here's the original:

and here's the repro...

I used a transfer technique (there are quite a few once you start looking for them) that uses freezer paper, inkjet printer and Microsoft word.  I recreated the box and fonts in Word, then flipped the image so it would transfer correctly onto the chassis.  I used a technique similar to that used in this blog: http://home-frosting.blogspot.com/2011/0...paper.html except I cut the freezer paper into a size just a bit larger then the image and taped it to a regular piece of paper (keeping the waxy side exposed.  I then printed the image onto the waxy freezer paper, carefully cut out the image and pressed it onto the chassis.  Its important to burnish the back of the paper with a spoon or hard round object to be sure to transfer as much of the ink as possible.  I should have pressed mine a little harder.  For a first try, I'm pleased.  I'll coat it with a matte clear coat to keep it from rubbing off.
