(Seriously though, I should ask the likes of Boot Lane Works about that..)
Never heard of the supplier, they appear to be UK-based and sell an assortment of things, including OO scale parts.
The kit looks rather well-designed. It's available in both 32mm and 45mm gauges as a complete loco kit, or just the chassis. In both 6V and 12V options.
If I hadn't started bashing an IP Huddy kit some years back, I'd give one of these a go. No connection to the seller, I just found them online.
