Anyone who has gone looking for dimensions to build either a model or pattern for a Westinghouse air brake cylinder has been exasperated to fine detailed cut away drawings of the different style cylinders published in the Car and Loco Cyclopedia, among other places, that are completely dimensioned using letters keyed to tabular data, without the data table being included. Years ago I was able to find the tables for type K and L tender cylinders in a Westinghouse Air Brake Co. catalog from mid century.

Would anyone have similar data for the type N (with triple valve seat) and M (without) passenger car cylinders that they could scan?

Either PM or e-mail me.

Thanx!
