eBay Find: MSM-5A Incandescent Display
I just ordered a pair of Alco MSM-5A incandescent indicators from seller hp2114b on eBay. In retrospect, I should have purchased all 5 so I could make a clock out of them. The remaining 3 units sold out within half of a day after I made my purchase. At $10/each, these things were very reasonably priced. The are 7 segment displays where each segment is its own discrete incandescent display in its own envelope. According to the description, it is even possible to swap out the bulbs with a similarly shaped light source, such as an LED. Below are the auction photos. I will replace them with my own photos once they arrive.
