A quite deep-boxed 'prairie schooner' or covered-wagon, which has long slots for the cover to attach to the body instead of the plugs most other makes use, along with the nice touch of the first tilt-hoop being left bare.
I'm sure I've mentioned a draw-bar and horses here before (when I was asking for the translation on the SGDG mark) and it seems to be the same as these, with the skinny copies of Beton horse.
A fine stagecoach; this particular model was heavily copied (in Hong Kong and elsewhere) in the same size (sub-50mm), with further piracies getting down to 30-odd mm. We looked at a JTC (probably HK not Japan) copy here and it also seems to have provided the model for Blue Box's team on their little red and brown wagons (ex-Crescent) in the small scale.
Brian's Berserker shows us how much smaller these are to start with! Interesting to note that the coach figures have plug-on hats (which always look a bit Mexican, especially on the copies) while the wagon figures seem a little better in the sculpting department?
