Scott Generating Set 2.75KVA (Scott PA engine) for the Kerrison Predictor Unit on the Bofors Anti Aircraft Gun.
Hello I have joined the forum and wondered if one of my engines/generator may be of interest and I would also welcome any advice or help with its maintenance/operation/history. I would also welcome your thoughts on keeping the original paint/patina with a thorough clean up or whether I should go for a full repaint restoration. I have started to give it a good clean/degrease and it is coming up well (I will post more photos once complete if these are of interest).
I would appreciate if you have any information on the above engine/generator or indeed if there is any history from it's War Department number and information.
I am looking for maintenance or workshop manual information. What type of oil and grade to fill the engine with (it runs on 2 stroke but there is also a filler for the engine).
From what I have found I understand that this engine and generator were used to power the Kerrison Predictor Unit and the Bofors Anti Aircraft Gun in WW2.
The details of the engine/generator and its WD plates are:
- WD Number: B 5755
- Scott-Generating Set 2.75KVA, Spec RE/P/3702, (electrical) drawing number 40241, the year is 1941
- Generating set 2.75KVA, 130v 3PH, 50~, 12.2A, 0.65PF, rating 1/2 hour Scott Saltaire
- Under the WD number there is an inscription which appears to be: An image of the Crown with a line underneath it and with the number 521 underneath that. I think this was for the 521 Coast Regiment Royal Artillery which was based in Newhaven, East Sussex.
Any information/history you could provide of this individual item would be greatly received or indeed if you could advise who/which organisation may have some specialist knowledge that I could contact.
The good news is that the engine and generator worked however it now needs some fettling to have it running again. There is a good spark and compression it just needs some time spent fettling. Unfortunately, as usual other commitments can take precedence although I should have time over this summer.
Thanks
