[Premium-Rx] 1.4MHz IF Filters

[BillT]

Hi all
Has anyone compiled a cross reference of the many brands of these particular filters?
I have made this attempt and have a partial cross reference list available.
These filters were used in Racal, Dansk, Eddystone, Skanti, & Marconi receivers
to name but a few. 
Brands such as Racal, Cathodeon, STC, NDK (Nihon Dempa Kogyo),
HyQ, CR Snell, Crystal Electronics supply/did supply such filters.
