What are the existing rims? If they aren't ruined, I'd probably stick with them. They are closer to original than anything you can get today, the have a connection to this bicycle, and you already have them. Rebuilt with news spokes and new tires on the same hubs, cleaned up ad polished, you'll have a very nice set of wheels.
I looked at the rims on ebay. They look fried. I would definitely keep them, but I don't think I would want to ride them.
I recognize the decal but the name escapes me at the moment. No doubt they are original to the bike. Rare like hens teeth.
