Make sure you 'tune' those wheels up before putting them to use. Just so you know, those aren't factory Jag wheels. Jag never used a bolt-on wire, the factory wires were all spline-drive knock-off style. Jaguar discontinued wire wheels in the early '70s because of issues with them going out of true but because of customer requests the dealers would install them, usually Tru-spokes (source for spokes), although even the dealers finally quit doing that as they had to eat the 'warranty' issues. Loose/broken spokes aren't uncommon, make sure the spokes are properly tightened. You find these on the used market pretty often, usually because they were removed with trueness issues. Trued up and used on a lighter car (under 3000 lbs, and avoiding 'spirited' driving) they'll be fine, heavier cars not so much.
I also suspect that you'll need to de-lace the wheels to replace broken spokes. Check u-tube for how-tos.... The problem with these was they were only 40 spoke, which wasn't enough for the car's weight/intended use. If they went to 60 spokes, they couldn't get enough room to access the lug nuts.
