[Boatanchors] WANT please: Documentation Simpson 260 Adapter "Communications Tester Model 658

[Les Zwiebel WB6ORZ]

    This unit clamps on the bottom of my 260 VOM. It is called  "Communications Tester" Model 658. It measures SWR -RF Power -% Mod -RFS. It has a slide rule on it's face and a telescoping rod antenna. It has SO-239's on either side, and jacks for RF out and also AM Monitor. It has scaling up to a KW. Sadly, Simpson doesn't have any paper on it.
    Thanks in advance for any info. at all.
    Happy Holidays to all.
