Thanks for all the kind comments, I'll try and answer the questions
As I said above the build for this one will be going into Model Engineer Magazine with some additional stuff on their forum/website so don't really want to go into too much detail here on the public forum at least.
Finish is just rattle cans and quite a while spent on prep underneath
The drain cocks were cut (manually) from some 5/8" square brass that I had and only the thread for the nut soldered on as there was not room to turn a die, all went well except a bit of distortion of the taper reamer when quenched, see below
Lining was done in acrylic gold paint with a ruling pen, the curves on te fluwheel were simply done by using a french curve to guide the pen.
The brass ball on the top is a cylinder lubricator and would have oiled the piston, its based on ones that I have photos of on full size Tidman engines.
As I have used this small selection of photos on various websites already ther can't be any harm in showing them here which may answer a few queries, then again I expect it will raise a load more
