I've been in the HO train hobby forever (since around 1956); and, in 2016 I scanned all my structure kit boxtops and instructions (I always save them after building) and sent them to the
http://www.hoseeker.net/ site. My stuff alone added about 45% size to the site. If you couldn't find an HO structure back then, you probably can now! My scans labeled "collection of Swamp Daddy"; took many weeks scanning some every day. That is
the site for finding data on HO items of the past. Hoping my oldies stuff will help some modern modeler.
have fun all, Swamp Daddy :King:
