[Boatanchors] RCA mechanical filters

[Nick England]

A fellow cleaning out his (ex-RCA) Dad's estate sent me a message
saying he has a couple of RCA mechanical filters in case you need one
of this type. RCA MFU-250-1 - these were used in the SSB-1 xcvr and
maybe other gear?
center freq 251.95 kc, bandwidth 3.25 kc

Let me know and I'll pass along your e-mail to him.
cheers,
