Dawe 3001A Frequency Counter

Behold the Dawe 3001A Frequency Counter. It was an eBay steal. No one else even bid on it.

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. ⏰
