J52/3 Injectors

A friend who models in 4mm scale asked me if I would draw up some injectors for GNR tank engines (J52/53) so in between working on the lathe improvements while waiting for bits and pieces to arrive through the post I had a go.

He provided me with an annotated photo to work from which didn’t have every dimension on it so while I don’t think that it’s 100% accurate, it’s good enough for small scales.

Of course we need a handed pair which was the last job.
