Default Noise Figure data for VHF TV and FM front ends

I interested to find manufacturers Noise Figure / Noise Factor information on all the various valve and semiconductor tuners that have been created from the 1950s to the early 1980s. That is, from the early days of the Clydon TV 5 (Band I only, PCC84) via the VHF/UHF semiconductor tuners of the Dual-Standard TV era to the dual gate mostfet units, beloved of FM tuner buffs, with valve FM tuners positioned in between.

I've got some information from the editions of Wireless World which the American Radio History web-site kindly makes available. However information on units like the "Fireball" TV tuner, let alone HI-FI FM tuners, still eludes me.

Any suggestions for where to look - and any actual information on specific units for that matter - would be gratefully received.
