Williams called them dummy upgrade kit.

It seems as if the kits are no longer made, as far as I can tell. They started out on eBay at around $75 and stayed there for a few years. Then they jumped to around $150 for a while. Then they jumped to around $225! Yikes!

Then the sellers started to put the wrong pictures with the kits and that caused a lot of confusion, as there are several types of kits. Going from memory, here are some of the types:

-four wheel low profile flywheel = F3

-four wheel standard flywheel = F7, GP 7/9, Baldwin sharks, ALCo FA and FB, and some modern types of locos

-six wheel center wheel blind = E7, EP5, ALCo PA & PB maybe others

-six wheel rear wheel blind = other six wheel modern loco types

I don't run any locos with prototypes newer than 1952, so I do not know the designations for SD, AC, Mac and other types of diesels.

I hope this helps
