This is just one of the unusual things we get. It is an old borescope made by A.C.M.I It's a Model 12a. The light still works and there is even an extrta bulb. 49l is the bulb type. Please let me know if you know more about it. It will be forsale in our former bid window. And remember,if you dont like the price,make an offer. Most things in the store are negotiable.
