Hi all,   Whilst realising this isn't exactly a straightforward question since the answers depend upon the locos/carriages being modelled, does anyone know over what sort of range (min/max, average) the width of lining should be please? The reason I ask is that the lining pen I have available only goes down to 0.25mm (3/4" in real life). I'm pondering making (or getting made) a new nib sized at 0.18mm (approx 1/2") in real life. In reality the paint line tends to be a little wider than these
