Bladeracer is most likely correct about the wheel being from a 954 or a 929. Its easy to tell the difference between a 929 and 954 wheel. They are both 3 spoke but the 954 wheel should have cutouts in the center, dime size holes near the bottom of the spokes and around the sides where the brake rotor mounts to the wheel. You should be able to see through the center of the wheel when looking at it from the side.It probably is a 954 wheel that has had the bearings and centre spacer replaced to fit an earlier Blade.
A photo is probably all that's required to identify it.
