Graflex Graflite Flash adapter

Flash bulbs are costly, cumbersome, and inconvenient. I wanted to use electronic flash, and still maintain the vintage look. Unfortunately the Super Speed Graphic does not have a PC sync on the shutter. Instead it has a proprietary three pin cord that plugs into the body of the camera and connects to the flash gun with a Y cable. For this setup, I 3D printed a cold shoe adapter that locks into the flash bulb socket, mounted a hot shoe and the smallest electronic flash I could find on Amazon. Attached a two prong cable to the the extension port on the flash, to the PC on the hot shoe. It works perfectly
