Hi John,
this is only a guess but GLR Distributors Ltd do a wall engine that may be the one that you are refering to. My guess is because I have just bought from GLR his Tina mill engine and the instruction come with drawings that have recently been updated by a guy with either the same name or similar. The reason for being a bit vague is that I am at present away from home and can’t get to the information.
However Pete of GKL may be able to help here because if it is the same model then his instructions for Rachel may be copies of the original ME articles – they are for TINA.
I’ve noted on GLR Distributor’s web site the following:- “RACHEL” WALL ENGINE-Unusual wall mounted steam engine, based on drawings by Otto Lilienthal of Germany in 1882. Cylinder 2 mm bore x 40 mm stroke, Flywheel 170 mm dia. Drawn in metric, building instructions included. Try
Hope this is of some help.
