[Premium-Rx] Collins Filter Information?

[Glenn Little WB4UIV]

The chart that I have does not list this filter, however, there are filters 
of this series listed. This should be a 300 CPS BW filter, if the number is 
F455B-03, if the number is F455B-30, the BW would be 3.0 Kcs. There is 
listed a F-455-B-31 filter that is 3.1 Kcs BW. This is the filter supplied 
with the 75A-3 receiver.
