I've now had a look thru your extensive 7mm catalogue. I'm looking for wagons in 3.5mm with both body and chassis in plastic. I'm happy to provide fittings like buffers and couplings myself. I see you do a 1909 wagon, 7 plank FRWC 48 which, if it's on a 9foot chassis would be fine for private owner pre- grouping.
I should also point out that my principal layout is GNSR so I would be overjoyed if any of the GNSR wagons like the box van,brake van,cattle, coke and 3 plank were to become available in HO. I've made the bodies of the first three in this scale in the past myself in either brass etch. 3D plastic or resin but have always been daunted by the lack of an appropriate plastic chassis in HO for these GNSR models, Scotch brakes and all. As I say I would welcome any of these in 3.5mm.
