Thanks, there was unanimity, all thought it was likely the 2.7 khz 4 pole
filter found in earlier rigs, like the Corsair I, and Ken, W8EK confirmed that
48057 is the T-T internal part number for the filter.
Some asked how I like the INRAD 400 Hz filters. I do, but haven't had the
opportunity to compare them to the T-T/NS versions. With all the filter
positions on the Omni VI+'s, it might be fun for someone to load each IF with
one of each and see if other ops (unaware of just where the filters got
placed) can tell the difference and have a preference.
Thanks & 73 Folks!

If it only has four xtals in it, it is the original SSB filter than came
in very early Corsairs, and also very early Argosy. The filter was often
replaced with an 8 pole filter for more selectivity. Sometimes the user
would move the 4 pole filter (like you have) to an extra empty slot, and
have 12 poles of filtering.
By the way, we sold quite a few of these units, and were also a warranty
service center for TenTec "when TenTec had dealers."
The 48057 is TenTecs internal part number for the filter.
