In my humble opinion these are much nicer looking and similar quality and weight to the revolutions you desire. They predate the Revolutions by several years. I have owned and used both.
The Americans are very strong wheels although they do tend to bend without cracking after decades of banging curbs on race cars and being roughly handled by trackside tire machines. My guess is that at least one of these is bent if carefully checked with a straight edge on a hub, although probably not preventing it's use. These, like the Revolutions were specifically made to clear the large 750/101 series brake drums. Vintage Revolutions are very nice wheels but are not going to have a tapered insert either. They will require a similar mag wheel nut, but with a different outside diameter. You may have to have nuts made or turned down on the od to use either American or Revolution wheels.
I have two sets (8) of Americans like these that I am not currently using. However I wouldn't mind putting a couple just in case spares with them in the attic to keep Mr. Murphy off my back.
I think you should use them, but if you have your heart set on Revolutions, I will leave you and the poster with the pair of spares, offers via Private Message.
