OH yea! did restoration on a 750 HP version...though Not Plenty & Sons!...This one makes me think of the "Ena" Bob! Dave
Steamer - which 750hp did you get to play with? It's making mine feel like a learning toy...
Wooohooo! We may be getting a good result here - SPX think they may be able to help! Thanks again Rod
Well that SPX link has done the trick! The guys there sent through photos of one of their engines that sits in the yard, plus put me onto the Berkshire records office who held the company records. The office have just replied with the Plenty info, and searching based on bore & stroke gives a choice of six engines, so now to cross reference those to the document list Beautiful engines, Steamer - thanks for the photos! Where are they now?
For what it's worth: there was always a great competition in Newbury to get an apprenticeship with Plenty. One of my school-chums was lucky enough to get a place. At the end of it he received his First Class Machinist papers and his cards, The manager told him to go away and get some experience with other companies after which Plenty & Son would welcome him back. He always said that after Plenty, the other companies tolerances seemed wide-open and sloppy - he being used to tenths of thous.When I used to cycle past, their yard was full of rusting casting. Duncan later told me they would rough-machine each piece, then set the castings outside to "weather" (stress-relief the natural way) for two to three years before performing the finish machining.GeoffOld NewburianThailand
