Thanks for the comments guys.
Tom from what I know #3 was not used much if at all in the early days at Knotts. So for about 20 years she didn't run. Later she was moved to a remote section of track across from the depot for display. In 1973 I think it was 41 in the shop for an overhaul, then something happened to 340 then it needed to be shopped. So with no loco for the up coming summer they looked at the goose. Long story short it was rebuilt and ran that summer, and maybe that winter until either 41 or 464 was ready.
Then in 74 or 75 the goose had the GMC 361 replaced with a REO 6 cylinder engine.
