[TenTec] Need info on Filters

[John Farler <k4avx1@windstream.net>]

I have two (don't ask me where I got them) old Ten Ten crystal filters I 
need help identifying.
They both are on the old standard (through at least OMNI VI+) filter 
circuit boards with the
4 pins.  They are 4 pole, with jumpers on the board to make a complete 
circuit through
the empty xtal slots.  The number on an end crystal is 48057.  "NS" is 
on top of a middle
crystal, and the other end crystal has 9002 on it, which I assume is the 
center frequency.
I can't find the number anywhere, in the virtual museum, nor on the data 
in the Ten-Tec
Wikki.  Does anyone on the list have any info??

Thanks in advance....
