Jim,
Since you have this discussion in the 'Live Steam' forum, I assume that is all you are interested in.
The kits that Accucraft produced in association with Aster do of course have their assembly drawings.
I assume that those locomotives that were made just by Accucraft as ready-to-run do not have the same documentation, although one would assume that those in the factory assembling them must have had something similar to follow.
Did the Ruby kit have drawings?
Cheers,
