The little engines ..3/4 inch....4-8-4

Working on a 3/4 inch little engines cylinder block, from the reprinted drawings in book form....the drawing dimensions leave a lot to be desired. On the cylinder liner...they give no dimension, on how far the square ports are from the end of the liner....their size, or a center to center distance o...

Hope someone buys it.....in the meantime it's back to my pattern making days.....with some good iron foundries in my area, getting castings is not a problem
