Denford Software & Machines

I recently purchased a Denford Easiturn 3 CNC lathe with a Microkinetics retrofit with Turnmaster Pro software. Everything seems to work fine and I would like it to be able to cut threads, but the original spindle mounted sensor disc is missing. I purchased the Microkinetics threading package which includes their sensor assembly, but it doesn't fit the Denford. The wiring seems to match the Denford's reader head configuration though it may not be compatible. I'd like to attempt using it if I can locate a used disc or even a picture with dimensions to fabricate one. Denford no longer supplies parts for this machine. I also have the original control pendant in nice shape to sell for offer if anybody is looking for one. I'm in the north eastern USA.

Any help or advice greatly appreciated.
