You lucky man!
I'm no expert on these things, but as long as it's even half right, it's got to be worth that and more.
Nice one!
P.S. Got the 140. Will have to get it working (hoping it's just the pump seal). But boingers are my thing, really, so if you ever get the boiling bol&£ks for a 140 and you have a nice little Cadet / Merlin handy, would always be happy to do something!
