[Test-Equipment] Identify antique test gear

[John King]

A friend (I think) saw fit to give me three pieces of test gear. I would like to learn the period of manufacture of the following gear, if you can remember it and are familiar with it. About when was it made and in some cases what is it and does it have any boatanchor utility for the ham with a lot of old tube type gear.

1. Supreme 504 A "tester" appears to be a tube tester with roll chart?

2. TS 532/U multimeter with MX815 multiplier kit. The name Mitch is painted on its' face.

3. Fisher M-Scope made in Palo Alto, Ca.. Not an oscilloscope. Has a meter on it and has instructions regarding     using it parallel to the earth and is said to have readings and tone changes near metal and minerals, 

Just curious if any "old timers" have encountered these pieces and if you know much about them. Please share the info if you have any. Thanks and 73, John, K5PGW
