MatchFuzee Posted November 8, 2019 Share Posted November 8, 2019 Assuming, that it is a Briggs & Statton, hopefully you will be able to find the engine date here:- https://www.flywheelers.com/pages/BobLearned/mdate1.htm Quote Link to comment Share on other sites More sharing options...

Martin, the manual is dated 1943, so it is very likely a WW2 era set. Quote Link to comment Share on other sites More sharing options...
Adrian Barrell Posted November 9, 2019 Share Posted November 9, 2019 (edited) According to my technical literature, the generator is made by Pioneer but the engine is made by B&S. The PE-77-A to C used the model IL, the D and E used the model N. Edited November 9, 2019 by Adrian Barrell 1 Quote Link to comment Share on other sites More sharing options...
MatchFuzee Posted November 9, 2019 Share Posted November 9, 2019 It may have been used to power a Teletypewriter TG-7-B The Alaska Aviation Museum has a Briggs & Statton engine powered Pioneer generator and a Teletype Model 15:- https://www.wy2.org/engines/engines-pe-77-d.php Quote Link to comment Share on other sites More sharing options...

Thanks Adrian I actually looked briefly at this generator yesterday and did not think it looked like B&S and the engine data plate was not easy to read, so my mistake. Thanks 😊 1 Quote Link to comment Share on other sites More sharing options...

MatchFuzee Posted November 9, 2019 Share Posted November 9, 2019 MartinN Unable to see the engine model number, but if it is 'I' as per the Alaska Aviation Museum's one, the engine was made in July 1943. July's serial numbers run from 76259 to 78780 incl. with a total of 2521 produced, and yours being the 388th made, it would have been made in the first week of July.
