These unpainted cast metal figures and kits are typical of those offered by countless British cottage industries. Apparently at one time they made a number of N Scale kits, including L44, farm tip cart and horse (below); now they're down to AN1, one lone horse. Image scrounged from eBay.
Where to Buy
While the horse is still available directly from Dart Castings, the tip cart kit can only be found on eBay—if you're lucky enough to catch it.
