Yours has been cannibalized to the point it's now a cool bike, but not a collectible. The rims are unsightly, but they're also steel and surprisingly strong--I expect the wheel can be made rideable. Replace the Uniroyals with any 26" tire that is measured in DECIMAL notation (not fractions). The internal bearing groups could probably stand some cleaning and re-greasing, as well. If you have those skills, great. If not, folks here will instruct you, or point you to a good source. You said the wheels were not quite true, but this can sometimes be mistaken for hub bearing wear. Lift the bike off the ground and wiggle the wheel side-to-side. If it moves, the axle cones are loose and usually just need snugged-up.
