 * Estate find LIVE STEAM drawings 3/4 inch scale Boston & Maine 4117 4-8-2 R1d class by Al Armitage. Al Armitage was a master designer and draftsman for a lot of model firms as well as magazine work. he was a professional model builder of high standards.  He was involved in the Live steam hobby in the 3/4 inch scale line. This is his design and workbook for his 3/4 inch scale Boston & Maine 4117 4-8-2 R1d class.  I have not been able to find out how far or if it was finished let alone its final disposition after his death. But there is proof that it was started as notes state what was drawn, cast, machined and its prices! He did a lot of work for Precision Scale Company of brass model fame. They were coming out with a small line of 3/4 inch scale brass castings, air pumps, headlights and such. I believe Al was designing this locomotive around some of those parts! Sadly he had not completed all drawings yet. There are some blank sections. Inside of other sections he has list of drawings(prototype) and his model drawings listed. These are all original, some pencil, some ink on paper, or the old clear plastic.
