Hi RJD ~ Welcome to the forum!
Kind of a philosophical question really. It depends on your
1)general motivation [are you a collector, seller, player, hobbyist, etc.] &
2)specific reason(s) for wanting to restore (or not) THIS drum.
For example: I'm a musician foremost, so generally, I fix 'em so I can play 'em. I'm not an active collector (not always on the hunt), not a seller, but I do like to work on drums in a hobbyist capacity.
On the "specifically THIS drum" side - the drums I've worked on (and future ones) all have some personal value and meaning - my Ludwig Standard snare was a gift from a now deceased friend, my cool Rogers marching bass came from another friend's barn when his dad died, and yet another '50s set was my dad's - you get the idea.
As you probably know, a resto project can be an investment in time & cash, as well as a test of one's skill (and maybe patience) ~ not to mention those around us enduring our "obsession" ;)
Are you after it being functional, or a total "period" restoration, or ????
I guess the simpler question is - what's it worth to you?
