Displacement Lubricators

[mossie]

Hi All

I am building a white metal kit of an N1, non condensing, by McGowan Models, on a modified Dapol N2 chassis. This is my first go at building a kit, super gluing not soldering, as my slodering is not very good yet.

My question is this, is it possible to buy in 4mm scale displacement lubricators. These fit on both sides of the smokebox of the engine I am trying to model. Or does anyone know how to make some, or point me in the direction of a article or book that show how.

Regards

Richard
