Your info on the loco pictures is and isn't correct. The photo is of second 401. You see five of the original class 70s were standard gauged in 1888 as 2-8-0 switchers and re-numbered. When they were converted back to narrow gauge they received 400 series numbers again but not there original numbers. The loco in the photo was originally the 402, when SG it was 800, then 401 after converted back to NG and eventually became 341. The original 401 was also one of the SG locos. It was 803, then 405, then 345. Make sense yet?
I have been working on Bachmann about straight side tenders,but its a long shot.
All of these photo's are from the narrow gauge pictorial vol XI.
