if in doubt I have a new set which I could draw up and then we could get a local sheet metal place to laser cut and pump out  

Might have to let the blades be finished and issued first though.

Could even develop a 90's Bally "LE Stern"ish one with the flipper button protections ?????

Mate, that sounds like the way to go, and with your background in CNC, I'm sure they will be cut to perfection.

This could be a good sideline from you for the community - I have a shopping list of bits that are just waiting to go on the laser cutter.

SCODS - Swinks Cut On Demand Service. Just grab yourself a pair of steelcaps and away you go.
