I have a copy of D.L. Ashton's "Stephenson's Valve Gear" (24pp) and I'm now in need of his booklet (w/emphasis on LET) on the Walschaerts gear (16pp). I find that the two booklets have now been combined into one publication and now sells for 15UKP. That's $30+/USD, once post is added, and is quite a lot for a booklet of no more than 40 pages and to add insult to injury the only U.S. stockist I could find (Powell's) wants $44!. Insanity. (I know, I know, the man must earn his daily pudding.) Regards, Harry MODEL ENGINEERING DISCUSSION LIST.
