Turns out it's a Covel Type 6.
With my brother's help, and his MASSIVE, solid engine hoist (4"? thick wall square tubing; the most impressive engine hoist I've ever seen) we got it loaded onto the trailer along with some other equipment he passed on to me. Then with a hand truck, several ratcheting cargo straps, and my wife's help to tip it back, go slowly down the ramp (she was on the side, not in the path of potential injury), and lower it gently, we got it unloaded. Getting it up onto the nearly-as-heavy (well, maybe 50% the weight, but still very heavy) base will have to wait for another day. He also gave me a Harbor Freight truck bed crane that he doesn't need anymore since he has the hoist and a gantry crane in his new shop. I'm going to figure out a way to rig that up to get the grinder onto the base.
Generally it seems to be in very good shape. The table transverses VERY smoothly. The crossfeed moves okay, but requires a bit more effort. The vertical movement is quite tight. I didn't force it, just tried to turn it until it was clear that it isn't moving freely. As I type this I realize there may be a lock/clamp screw or whatever that is preventing it from moving easily. Didn't occur to me to look for one, I was just checking it out for a minute while waiting for him to grab the chain to lift it into the trailer.
The power switch is missing so it's hardwired to be always on. There's another power cord there for something else, perhaps an old coolant pump? Haven't spent more than 4 or 5 seconds on that.
The grinding wheels (2 mounted together currently) are in poor shape, but should clean up well. They seem rather fine, but I need to track down the arbor wrench/key (what's the correct term?) to pull it off so I can see the label to know exactly what is on it. But I suspect the fine grit wheels may have influenced my brother's opinion of this machine being not very useful. The whole time we were loading it up I kept looking longingly at the mill in the other corner, but he's keeping it. Someday...
He also gave me six quarts of MasterChem A/C Flush (80% Heptane, 20% Isopropanol) that he doesn't need anymore. Should work very well for cleaning this thing up. Doesn't leave a residue like most of the other stuff I was thinking of using.
Anyway, lots of work ahead. I haven't found a manual yet, but I've only spent about 10 minutes searching so far. If anyone has one or knows where to find one I would GREATLY appreciate that info!
