This is how I found Mad Modder, I should have posted earlier.
I used to build Alexander Engravers and I may have built that one, is there a date on the plate?
One of my first jobs was fitting the name plates, it was a nightmare for a beginner like me, the drill would sometimes wander, or cut oversize, or sometimes the PK drive screws would break.
The "motling" looks like mine but we were actually encourage to keep it uniform.
If I was younger I would have loved to do those CNC conversions.
