The counter consists of two separate units. The top is a fully self-contained counter module which attaches to the "front end" on the bottom via a short cable with what look like DIN-5 connectors.
It's hard to believe that three years have gone by since I took the first photo. The Nixie® tube on the left displays zero and two whenever it's supposed to be zero or two. There may be an internal short in the tube itself. I need to check that three years from now. ⏰
