I'm guessing an 8-30 from the looks of it. Worth saving and you could probably buy it right. The overhang tone arm support looks like it is swathed in tape or something, so may need replacing, but nice reproductions can be had for not all that much. And looks like it might be walnut, which can be quite nice when re-lacquered. Original type grille cloth is almost impossible to come by now, as the company making it went under a couple of years ago, but you should be able to find something close. The missing feet are just simple bun feet, so shouldn't be that hard to turn or get made.
