Rebuilt Merchant Navy
Pacific Locomotive

The only model in our range that has not been designed by us, this was serialised in Model Engineer magazine starting in October 1984, Vol 153 No 3739 and designed by Keith Wilson. This is the model that everyone wants to build but very few have the staying power. It is very complicated, it would be foolish to say otherwise, and is probably best suited to the experienced model engineer who already has an engine to play with.

The engine has three piston valve cylinders which are fully cored and is over six feet in length, the weight of the engine and tender is in the region of three hundredweight.
