Questions about crystal filters on Heath product line

[Bob Groh WA2CKY]

Well, I'm feeling a little stupid.  It turns out that there
have been lots of different crystal filters used on the
Heath SB-xxx line although it looks like the biggest
difference is mechanical.  Has anyone come up with a list of
part numbers, electrical specifications and radio's that the
various crystal filters were used on?  I have a start based
on my two radios (an SB-100 and a SB-303) plus some other
filters I have in my parts box.  All are for 3395 kHz IF and
all (??) seem to be 2K ohm in and out impedance.  What I
have so far

404-283    SSB filter, smaller case  Used on SB-303 note 1
404-548    CW Filter, smaller case,  Used on __???____
404-284-1  CW filter, smaller case   Used on SB-303 note 1

404-200    SSB filter, large case, used on SB-100 note 2
404-M201(?) AM filter, ?? case, used on SB-300
404-200     SSB filter used on SB-300 note 3
404-202     CW filter used on SB-300  Note 3

Notes:
1.  Also used on SB-300,301, 310 and 313 according to Penson
2.  No room in SB-100 for CW filter (??)
3.  Yes, this is a conflict with note 1 but seems to be the
case??

So I'm throughly confused.  Don't have manuals for most of
these rigs.  All help and information throughly appreciated.
