[CQ-Contest] Difference between the ICE 419 419A & 419B bandpass filters

[Paul Erickson]

Can anyone tell me the difference between the various
models of the ICE 419 band pass filters?

So far a web search for the manuals has turned up nothing,
and emails for clarification to the manufacturer go unanswered.

Thanks in advance.
