Sumpter 250's duff challenge

[ezdays]

How long would it take you to do one of those out in N scale Pete?

:o I would guess...........about twenty minutes longer than I have left to live ! hock: The HO one has been almost that long, waiting for the "Duff Challenge" to come along, so I could get it moving again.

It would be Nn3, so it would have to be based on a Z scale loco frame, and drivers.........Where did I put that 100X Optivisor?!

I'm thinking there's little value in a 100X, maybe a microscope and some tiny robot fingers might be more in order. I envy anyone that can do this at any scale.
