Like DUH, but my Alfa is homemade too, in larger numbers of course.
Just thinking if it is a Mark IV, there is possibly a MKI, II and III and maybe a couple of each of them (or not).
Just putting it out there in case it stirs a memory.

I couldn't find any mention of it in any of my old rallye books. It's most likely a custom homebrew. It uses Veeder-Root counters like just about every computer of the era, and the bank of setting dials looks what I've seen on Tommy boxes. It might just be a rearanging of someone elses components. Could we get a clearer photo of the front plate?
