[Steam-engine] Lead on slide valve.

[Richard Strobel]

Jim, Andy, and Francis, I appreciate the reply..also the off-list one!! 
I've ordered Croft's book and Rose's book I should get after the first of 
the year as it's a study guide for steam school at Rollag, which hopefully 
friend Corky and I will be attending next year.
It's all apart now and we're starting from scratch.

Thanks again,
Rick
