I have list of Altaya models available, No.1-70, but generally its just an Altaya number and name of the model.
Also I´ve got excel HM models database, some 660 rows, which I can provide to you, but from January 2018 its not updated. For my purposes, all I need to know about HM production I find on Hobbymastercollector site.
Complete Century Wings production you´ll find on CENTURY WINGS Aircraft Diecast Model | Home
, same for Air Commander Air Commander Heavy Metal Collection
, but these sources you probably know anyway, same as Flying Mule.
But with TFM I always have problem with their Search function finding discontinued models. I better search TFM site via GIS.
Maybe if you post your database here on the forum I´m sure many collectors will add their comments and help you to keep your database more complete, mainly in 1/72 scale, 1/144 is not so popular.
