I recently completed these three wagons.
Two BR 13ton medfit from Parkside Dundas kits, both with some additonal brake detailing, one with 51L axleboxes. BR Medfits spent most of their life in non-revenue use so naturally this was how I wanted to model them, frustratingly no specific ZAV decals are available so I modified some Modelmaster decals. Paint is Precision on Halfords undercoat. Rust is Rust-it
The third wagon is a Cambrian Dogfish with some additional detailing with brass wire for the vacuum pipe and I replaced the handrail with wire as well, paint is as above and decals are slightly modified Modelmaster apart from the Overhead Electrical warning flash is by Fox.

Next up on the workbench are some vans.
