At the time of removal, these things had suffered water incursion and the stencil-board (?) from which the numbers were cut was wet and adhered to both the front and the back glasses.  As I recall, the first two I attempted to remove were ruined due this "gluing" of the material, but the third one (this one) make it intact, with a lot of gentle nursing along.  Neither glass in the sandwich was broken, thankfully.

Plywood for building the light box came from Hodges Lumber on Shenandoah Avenue, and the molding came from Roanoke Paint & Glass at the corner of Kirk Ave and Commerce St, Roanoke, both now "Of Blessed Memory.".  Illumination inside is provided by tubular appliance lamps made for refrigerator use.  If I were doing the job today, the device would be lit buy LEDs.  I thought the contraption was ugly, so gave it to my son, who liked it.  And yes, at the lower right there is discoloration of the sandwiched material, due to water damage.

The four back members of the framing are rabbeted out so a Masonite plug can be pressed into the frame, to close the back side.

The LED arrays cost about one half the price of one incandescent automotive lamp, and have been burning continuously for seven years with no failures.  They are style G-4 (where 4 is the spacing between the contact pins, in millimeters,) and the bases for receiving the contact pins cost 12 cents each on Ebay.  Truly a Scotsman's delight !
