I have always fancied building a horse drawn vehicle or two mainly as wagon loads for several Open Carriage trucks that I have on the go. I was put onto the idea by a gent I spoe to at a show a few years ago who subsequently brought me a horse drawn carriage from a company named Brumm. Some of the Brumm carriages fetch crazy amounts of money but I found one that was being sold as scrap for not much more than postage and bought it to salvage the wheels from.
Although my photo is of a Great Northern Railway parcels van, the only drawing I have is for an LNWR example but they are broadly similar. I scaled the drawing on the basis of the wheel size that I planned to use (the Brumm Wheels are slightly bigger diameter than the LNWR drawing).
I drew out the body pieces in Inkscape and cut them out with the silhouette and got this basic body.
Please excuse the colouring of the photos as I had to adjust them to show the white against the white background…
