Zenith's best monochrome chassis they made basically that same chassis in dozens of different cabinets from roughly 1958 to 1974. They kept making slight revisions and changing the chassis number until N year 1966 then they decided it was perfect and left it be until they replaced it with Solid State monochrome chassis in the mid 70s.
The M in the chassis number indicates 1965 year. These sets are pretty easy to fix. There are around 2 multi-section can electrolytic caps on the chassis that should be changed each cap has 3-4 sections so probably 7-10 new individual electrolytics (1 per section). And something like 15-20 paper dielectric caps to change and maybe the K networks.
Tubes typically are still good, but if not are available for cheap on eBay and other vendors.
Analog TV is no longer broadcast so you will need either a DTV converter box and antenna for broadcast TV, a legacy signal source with analog RF output or a modern HDMI signal source and one or 2 small boxes to convert that to RF.
