Triang / Hornby single start worms

[uax6]

I've acquired a couple of Wills Crabs, some are complete and others are in kit format. The built up ones have 5 pole XO3/4's in them with brass single start worms on them. These obviously slow the drive down by half, and for the other crabs I'd like to get hold of some more please. These are identifiable by looking at the end of the worm. A normal worm has two starts visible opposite each other, single start ones, only have one start.

 

Does anyone have any going spare please?

 

thanks

Andy, 1/4 Whitworth brass bolts or studding drilled 3/32 make a perfect single start worm, I have made a few. Contact me if you wish.
