The only trim would be a (black painted) metal grill covering the 12", and an aluminum Klipsch inscribed, recessed, handle/grip.
The back plate, with two 1/4 inch insert/jacks, has a fuse (I don't know the rating off hand) and an old "Inspected by:" sticker with hand written signatures.
The boxes look like they are 1/2 in plywood, in a diamond shape, sprayed with black, industrial, paint.
Also, the 12" speaker magnet is stamped "5326".
I will post photos tomorrow.
Thanks very much.
