When we were there last winter, we were told the 500 had all its parts ready to assemble including a brand new boiler, but they were scattered around the yard. 201 was to be used as "special operations only" partially because its a small engine, but also because of the extent of the rebuild. 300
was running when we were there, but I dont know as of now. Not sure how long ago 400 went out, but the way I understood it, it will be the last to get attention.

PS, here is a still of 201 at Maydale last winter.
