Edward George AKA our very own Littlesamson now has the patterns for this engine & will at some point in the future (hopefully not too distant) be offering castings & drawings for this. Have a look at his web site for more details

Having seen this engine in steam twice now I can vouch for the fact that it runs as well as it looks & for a 6” scale it’s a relatively small engine & weighs in at about 16 cwt, perhaps a possibility for when I finish my Burrell.
