More 7mm Parkside mineral wagons in works at the moment. The leftmost one was actually started a good few years ago (you can tell by the yellowed glue and the rusty wheels) but never finished, while the rest are fresh out of the box. Note the sprue offcuts in the rear wagon, I leave these in as a force-fit to ensure the wagon sides end up bowed out rather than in - works a treat.
I have a bit of a bottleneck in the wagon works at the moment - Bill Bedford is threatening some new sprung W-irons for 7mm and I'm waiting to see how these turn out before pressing on. Previously I've used Slaters sprung units.
While we're on the subject of wagons, here's a size comparison between a 4mm Lima PGA and a 7mm equivalent. The latter was picked up secondhand and is somewhat battered - the kit is currently made by Nigel Stanley Models.
Finally, some ancient history that I've dug out for inclusion on another part of the site. The GWR brake van was the first ever 7mm kit I built, way back in 1984. I never did quite finish it (no weathering, or even varnish over the transfers) and one or two bits have broken over the years, but it's an interesting curio. These plastic kits were originally manufactured by Webster but are currently made by Peco.
