I would not want that one for parts, but they fairly frequentlly show up on the net,
and, not so much lately, in shows. The cars are often found separately, the engine
has many fragile and protruding parts...some or many often broken, including the cab,
as obvious in your example...so they have to be examined carefully. Finding an
undamaged engine is the tricky part. Tenders often have partial or complete lettering
obliteration....appears to be the norm. Oh, passenger cars often have broken stacks,
(2 each) but the stacks may be reproduced.
