[TenTec] Is Corsair 9Mhz IF filter worth anything?

[Jock Irvine]

I recently came across the original 4-pole 9 MHz IF filter from my
Corsair... I replaced it with the 8-pole filter back in 1997 when I first
bought the rig.  Is the 4-pole filter worth anything? I've never seen one
for sale.

Thanks and 73,
