3 1/2 inch gauge Lucky 7 - stock code 3727

A 3 1/2 inch gauge "Lucky 7", Don Young's design based on the Edaville #7 two foot gauge engine. A large narrow gauge engine in full size, it makes a monster of a thing in 3 1/2 inch gauge - nearly five feet long and only just a two man lift.

This engine was built by a prolific engineer, reponsible for a wide variety of engines from an 0-4-4T "Juliet"-derived tank engine through "Hielan Lassie", a 2 1/2 inch gauge Pacific and ending up with the 5 inch gauge Y6B I recently sold part built. Completed in 1990, it has spent the last few years stored in somewhat less than ideal conditions - the paintwork is pretty horrendous throughout, however underneath it is well made and runs particularly well, there's a clip of it in steam at the workshop here.

Silver-soldered copper boiler with superheaters, working pressure 80psi, feed by twin injectors and axle pump with auxiliary hand pump in the bunker. Cast iron cylinders with slide valves actuated by Walshaert's gear with pole reverser in the cab. Twin sight feed lubricators in cab.

Complete with a set of drawings, a fitted carrying crate and large quantity of notes by the builder.
