Rummaging about in some empty cartons I found a pair of 7mm NER D1/D2 bolster wagons components, there's a number of parts missing mainly floors and brake gear, which I will replace. Free of charge to anyone, all I ask is make a modest donation to your local children's hospice. It will need commercial wheels, couplings and buffers to complete although I can provide 3d printed buffers and housings if required, these would need springs purchasing unless your sacrifice doner steel buffers from another kit. D1 on the left has a fixed bolster beam, D2 has a rotating bolster on what the NER described as it's custom mounting. The photo is an old one, Rob Pulham kindly pointed out the brakes are on the wrong way around, so mine was stripped down and the brakes reversed.
