+1 on all written above. Hub is May of 1963 which would make this a '63 or '64.
Since you obviously dig the bike, I wouldn't worry about spending on tubes and tires, which as said WILL be more than the value of the bike. However, those are consumables, which any bike will need if it's to be ridden. Even a brand new bike with zero miles, stored in a climate controlled environment off the ground should get new tires every 7 years to be safe (none of us really do that).
That said, the bike has two different wheels, with two different types of tire. Right now this seems like your biggest problem. A lightweight rear, and middleweight front. The rear is correct (or at least the correct type), so factor in a new 26" lightweight front wheel as well. And match it carefully to the rear. This bike may take the British EA1 tire size with a 597mm bead seat diameter. No point in replacing the front wheel unless you are going to have them match.
All of that chrome will clean up surprisingly well. Many of us here use WD40 and 0000 steel wool on the chrome. You will be surprised.
The paint on this bike seems pretty darn nice. There are a few ways you could approach that. I think the WD40 / steel wool method I suggested for the chrome would dull this paint, but I use it for paint in worse condition. I'll let someone with more experience chime in on that (you will likely get several suggestions).
Looks like this bike has the twist grip shifter, but part of the cable appears to be missing. I have no knowledge about that, but it can be converted to the trigger style inexpensively if need be. I'm going to assume it will need new cables all around.
Then of course clean and grease hubs, bottom bracket, and headset (and hope they aren't damaged). Soak and lube chain, or replace if there are stiff links.
It's really not a lot of work for someone who has experience tinkering with bikes. From your post, I'm guessing that's not you, but don't be discouraged - we all started from the same place!
So if you want to keep the bike (you will lose money when you sell), are eager to get your hands dirty, and don't mind dropping at least $100 on parts, I say go for it. If you aren't sure, maybe pick up some 0000 steel wool, and WD40, and get started on the chrome and cosmetics first. It won't cost much to clean it up (aside from time), and you will get a feel for how deep you want to go along the way.
By the way, if your rear rim is EA-1 / 597 BSD (hopefully the tire is marked as such), I have a front wheel which will work, and I'm willing to part with it for cheap (although shipping to WA could make it not worthwhile). PM me if interested.
