A 1920s SHAY IN 3/4" SCALE (with instructions for scaling up to 1-1/2"). Fifth in this fabulous series of locomotive construction books, by Kozo Hiraoka, this edition has put to test and perfected each step of the building process. Instructions are concise and clear, and photographs by the builder are plentiful and sharp. Kozo Hiraoka's draftsmanship and clarity are without equal! This book has been confused by newcomers with Kozo's first book, Building the Shay, but this new book covers building a 1920's Shay. This earlier model Shay reflected the geared locomotive of the 1880's. Hundreds of detailed diagrams. 326 pages. Hardcover.
