I have a Collins Mechanical Filter  F455-FB-21  (6W2) - it looks new. 

Can anyone tell me what radio this was used in? What bandwidth is the filter? 
I presume it is a 455 kHz filter.

Does anyone have any idea what this filter is worth? I have two crystals with it so presumably 
it i was used as an SSB generator, or they were used as BFO crystals.  453.58 kc. and 
456.43 kc.

Thanks for any helpful ideas.
