Ah, Tom Cooper, wotta fellow, I met him in Diamondhead once, he was on crutches, had a terrible trip and was in an awful mood.
However, he did a lot for our hobby years ago. The Merlin Hunslet I purchased in 1985 overall was a strong, long running loco with wonderful gas and regulator control. The cupped "teflon" pistons lasted and lasted, the Merlin Matterhorn lasted me well too. I sold both engines a couple of years ago to put a few dollars in my wallet towards the Duchess. I suspect a book could be written about Tom! "The Good, The Bad and The Ugly!!" I remember the "Good" mostly!
