Today I attended a swap meet and purchased a set of 21" split rims. I was so interested on the latch where the ends of the rims lock together, that I didn't notice the rims have no lugs on them. I am looking for rims to fit 21" rims like the 26-27 has. Did anyone make a rim with no attached lugs which fit this wheel? If not, does anyone know what vehicle those might fit? I don't have them here so cannot post a picture.
May be Firestone rims ????
There are a variety of rims for a variety of cars and a variety of lugs to fit the various rims. There may be a name of manufacturer on the rims then you would have to find the corresponding lugs to fit the rims. If the assembly is not compatible the rim can turn on the wheel and tear the valve. Some have locking rims, some have one lug welded to the rim to prevent rotating.
Kelsey produced 21 inch balloon style demountable wheels and rims for Ford of Canada for a short time. They have a total of 4 holes -- 2 on each side of the split in the split rim for a special tool that is used to spread them.
1926-28ish Chevy used Jackson wheels and rims with the removable lugs. See:
Chevy Disc Wheel Split Rims
Posting some photos of your rims along with the width etc. would be a great help when you can.

Most car makes did not have lugs attached to the demountable rims. Most Fords, some Chevrolet. some Star, and some Overland are the notable exceptions. There were of course a few others, but most marques had loose lugs. So, your rim could fit any of a hundred marques from the mid '20s. Width of rim is very important for proper fit, as is whether the rim has a centering bead around one side that should fit against the felloe of the wheel (either wood or steel felloe). The Jaxon steel disc wheels used by Chevrolet and other GM marques (and others) during the '20s used demountable rims, no attached lugs, and no centering bead. They came in 21 inch size (as well as a few others) as well as different widths depending upon what year or marque they were intended for. The 21 inch Jaxon wheels have been adapted to use on many model Ts from the '20s till now. The wheels are fairly easy to find and get. The rims that fit them are a bit more difficult to get.
