I purchased the wagons below from a show at the weekend, and I'm trying to identify the manufacturer. They appear to be kit built, with a one piece plastic or resin body. Unusually, the chassis have A, B, C, etc - F moulded on them, and the bogies have 1 - 12 moulded on them, with corresponding numbers moulded on the chassis.
Any help greatly appreciated!
Thanks
Edit: apologies for the upside down pictures, not sure how to rotate them!
