A t-boiler shay handbuilt by old Ephram himself, and 30 inch gauge to boot!
Warning, if you start looking at shorpy.com, you won't be able to stop for hours.
IsnĀ“t that BABY - the first ever Shay built by Ephraim S. ?
This would be a pretty heavy kitbash-could be done but could be done basing on a HO Shay...
Cheers, Tom ;) ;) ;)
