I am sending you a photo of my 3/4 inch scale L.N.E.R. Pacific type locomotive which may be of interest to readers of The Modelmaker. I have been at work on this loco for the past two years, just spare time, and it is almost complete but for a few minor details such as handrails and lettering.
I purchased the blue prints, cylinders, wheel castings and boiler tube, 4-1/2 inch diameter, from England. The rest was made up from plate and rod stock.

I have had this engine on test a few times now and she behaved very well keeping the safety valve popping all the time. I can raise steam from cold in six minutes, which I think is very good because the boiler holds more than a gallon of water.
On its first test I had it steaming for 7 hours. I do not know how much it will haul but on a poor track and a board laid on the top of the tender it pulled 3 adults. I am now building an out-door track 80 feet long so I can give it a more thorough test. I have also nearly completed a passenger car which is 3 feet long and will carry four passengers. When I get everything fixed up I will send you some more photographs, and particulars.
