I've been after a Drewry and when I saw that Sparkshot do a body I raided the casualty department for an old 03 chassis with dodgy coupling rods.
Surplus bits removed and hard wired it ran fine on DC so I ordered a kit. Bits are here - I received 2 sets of buffers as there was a minor glitch with the first order.
All seems well...I shaved a bit too much off one of the internal mounting points during clean up and needed to add a sliver of styrene to keep everything level.
