Hello, I am reaching out to see if anyone here can tell me what bulbs may have been use in this lamp. Two bulbs were used in a 1960 era IBM lectern. The built in lamp lit the table top as well as to edge light the faces of the clock and timer. The attached images show the lamp used on the lectern and the front and back of the lamp's reflector. I'd appreciate any information you may have on identifying the bulbs or where I may be able to locate them. I don't plan on powering the bulbs of course, but would like to have them to complete the lectern. Thank you.
