I would advise another check that you can do before committing to new hubs.
You need to investigate whether the play is excessive and where it is comes from.
Firstly take the wheels off and try to move the hubs clockwise and counterclockwise alternately. If there is more play than you expect and a "clunk" , it is likely that the woodruff key is worn , or the slot in the hub, or more likely both. If so this is likely to be the answer. I don't know if a good machinist would be able to machine out an oversized slot in the (and half shaft?) and hub, but this could be a solution. Arwyn or others should be able to advise. Otherwise it looks like new hubs from Arywn's contact.
If the play in the hub seems "normal" then it is possible that the splines on the wheel have worn, but it is also possible that the splines on the hub are also worn (like Steve I thought the hubs should be stronger than the wheels ?) However in the 70s I remember Allon White replacing the hubs on my +4 racer and it also solved the problem as I used the same wheels again . If the play does emanate from here , try packing it with grease and see if this makes any difference. If so it is likely the problem lies in this area.
