There are a few web sites ,like this Tandem Associates one that give pretty good information and indexes
Tenders: https://www.tandem-associates....el/lioneltenders.htm
Main Index: https://www.tandem-associates....onel/lionelident.htm
However, I find these as other valuable resources of great PW information:
*Greenberg Guides (not the price guides)
*A membership to the LCCA to get the access to the digital copies of the Lionel Catalogs from the pre, post, and modern years (along with the Postwar Service Documents)
*Olsen's Toy Train Library (Freely Hosts copies of the Lionel Service Documents in hopes you will order parts from them)
