The removal of the drawings isn’t necessary, John. My intent was not to be nasty at all. Just to inform that copyrighted material belongs to the artist. Yes, the drawings are intended to use for model building and photo-copying is perfectly fine for the individual modeler to do. But re-publishing or selling by other than the artist is not OK. It is a fine and sticky line to be sure. In this case, please leave the drawing up. You have done a fine job worthy of note.
On another note, I don’t usually enlarge plans to build from. I just use the dimensions shown like a home-builder would do with plans for a house. If one has the proper scale rule to use, then it is easy.
I do not have a web site at the moment. That will have to wait for a while. I was piggy-backed on another site but the owner withdrew it, so of course, I lost it. I do sell 6 plan books and one for Gn15 also showing many, many drawings for vehicles, structures and rail items including locos and rolling stock. There are too many to list here as there are about 100 of them in total. If you can narrow the topic a little, I can list some for you. Rolling stock, tank cars, box cars, flats, town structures, etc. Most are drawn in 1/4" or 1/2" scales and can easily be copied to your scale if necessary.
Just send me an e-mail and ask.
Tom
