Re: T-12 Cylinder Cant

If you will take a long look at the Perry photo of the 169 on the Chili Line, the top of the valves line up with the flange of the cylinder saddle on the bottom of the smoke box, and all of the rest of the cylinder lines up with the valves.

Canted slide valve cylinders came in two types, one with the valves flat and only the cylinders themselves canted (Porter and Glover for instance) or the entire cylinder and valve assembly was canted.

If the valve covers line up with the cylinder saddle flange, then the valves are flat. If the cylinders then line up with the valves, then they are flat also.
