FS: Heathkit 400hz CW filter 404-284-1

[Dave]

Hello all,

I have for sale a 404-284-1 CW 400 hz filter.  Removed
from active service a while back and I'm sure is still just
fine.

See it at http://www.boatanchors.com/images/heathfilter1.jpg

As you can see there are some paint chips, but it is in otherwise
good shape.  I'd like to get $40 for it plus $4 in shipping.  Let
me know if interested.

Also, can anyone tell me what this OTHER filter is?  Here is a
photo of it:

I've had it for a long time, but I haven't a clue as to what it is
spec's-wise.
Does anyone here know?

Thanks,

Dave WB7AWK
