I remember ads (and a quick check
didn't find one) of them touting a really good filter made by
that company. But I'm pretty certain it was in the 5MHz range

You have a good memory. MHZ Electronics was dumping
5.9XX USB, LSB and CW filters in full page ads in Ham
Radio Magazine back in the late 70s or so if my memory
holds. I remember buying several of each for future projects
that never have materialized.
