Have made several of these in the past, both keyed and single dial combination. We picked up a couple of these dual dial doors at a junk store recently. The case is cherry with an oak back, oak splines. Decided to add walnut buttons(should have left them proud).
Bought the brass coin slot on line.a little WD40 and propane torch to turn the bright brass to the aged look.
Each door had paper Id tags , one being “paint dept” and the other “campus police” typed on, suggests they were part of a mail box assembly perhaps out of a college? I recreated tags to put over the original and added the combination. In this case 1 line before E and 1 line before S. a reminder for the owner but perhaps not so obvious to others. with the exception of a piece of felt on the floor, the inside is unfinished. A couple coats of diluted shellac wiped on followed by a coat of wax.
