Bill Lenoir introduces his Saginaw engine line September 1940 with the first of 6 planned PRR steamers ..the H10...to be followed mid 1941 with the G5 and E6. World War 2 cut short plans for the additional 3 steamers . Cast bronze boilers , chassis , tenders , kits sold for about $40.00. The line was fairly successive ...with far more H10 found today than the G5 and E6..
The Saginaw company went to Pioneer ( switch motors) in 1942 ..to sell down remaining inventory, whilst Lenoir is in the service .
By 1948/9 Bob Smith of CLW had the Saginaw patterns and advertises the 3 engines will be in production soon.
Best I can tell, the H10 returns to production in the mid 1950's with a modified chassis . E6 and G5 were never seen again.
I have the patterns for the H10, and it's tender ...and I believe one of the 3 steamers that was not produced ..a PRR ? ...it has been suggested,..a C1 or K2/3...
