Just curious. What plane will these be going on and when will you be needing them? Rumors are strong that someone will be back in production of these within a year.
Of course you could always make a pair of wheels yourself in about a week! Yeah, I know, you probably don't want to hear that.

Below is a set of 5 1/4" inch spoked wheels I made in about a week. They look a heck of a lot more authentic than the WB wheels and while one WB 5" wheel weighs 105 grams, my handmade 5 1/4" spoked wheel with aluminum (and wood) rim and stainless steel spokes (40 of them) and stainless hub weighs in at 102 grams! And this is with a heavy reinforced fuel hose tire. With the much lighter foam tires (show in the photos below) I'd guess the wheel is closer to 95 grams. And I wouldn't be surprised if I can shave off a couple more grams on the next try.
