Fisher Stereo and Webcor devices left from my dad

My Dad who passed away 4 years ago left behind some stereo equipment. Instead of trying to sell it I want to try and re-purpose it. I have found some manuals for some of the equipment but not all. I'm pretty sure there are three separate systems. One is a Kenwood system which I was able to find. the other is a Fisher system which I was only able to find one manual for the CA-857 Integrated Stereo Amplifier. The rest i'm not finding anything about.

I still need information on a Studio Standard system by Fisher: Stereo Turntable Model MT-857(C)/ Fisher Stereo Tuner FM-857/ Fisher Cassette Deck CR-W857.

Then I have a random Webcor AM/FM Stereo Tuner model 291.

Any information Is helpful and I appreciate anything that I could learn about these systems.

Thank you
