I have a six horsepower Lister CS that I found outside. I suppose you could call it a field find.
 I have one myself, a Lister 8-1 S-O-M.  and would like to pass this one on to anyone prepared for some considerable work and expense.
It has been in my shed for 16 years. There are parts missing and it needs lots more replacing.
The photo shows that. If you are interested please P.M. me for more details. Chris.
