I had a search round and this is the company making them.Wuhu
They must have a connection with Accucraft (US) somewhere or maybe they actually made the Ruby for Accucraft and now have decided to go direct.
I've also just seen this on German e bay.Wilesco
Don't turn your nose up at it.
Deciphering the German it says it's only been used once and sat on a shelf, is dusty and has no original packing.
They used to sell these years ago in Beatties as kits alongside Mamod and LGB.
IMO it's worth a pop at less than 100€ and some people have turned them into decent machines.
Here's a link to a pic of the original kit.
