I received a pair of axles and wheels from LZ Models courtesy of Libor that I married to a wooden and plastic frame that I copied from the Trumpeter gondola and made from timber and plastic.
In a magazine I saw a photo of an old wagon that had been converted to carry explosives and that was my inspiration. This was just an exercise to see if 1/35 rolling stock could be built . Nothing serious just a bit of fun.
This has to be one of the few 1/35 scratch built wagons around.
