The only correct way (without someone having direct knowledge) would be to acquire a period correct CHASSIS CATALOG.
...and ... They may be aftermarket. Aftermarket was big in that period. Does it appear to have ridges in the inward portion?
I don't have the original rings, when I brought the car home they were already gone. Either stolen or was left off when tires were put on the car at some point. Might have even came off when driving I know in the past trim rings and hubcaps that grabbed the inside edge of the rim were known for flying off.
I have the 1949-1959 Ford parts and illustration catalog and it doesn't list trim rings, I hit up a ford part specialist I know that is retired now he told me the following when I asked him about the lack of it being found in the parts and illustration guide.
At one time, the 18000 group was used for optional or dealer installed accessories: radios, heaters, fender skirts, wheel trim rings, "bed post" bumper guards, floor mats etc etc etc.
Later on, these 18000 group part numbers (except radios & heaters) were replaced by other part numbers that reflected the group they were used with.
For example, wheel trim rings became basic part number 1210
I looked in the 1949/59 Ford car parts catalog (printed 1964), there's no trim rings listed.
14" wheels were introduced in 1957 and used thru 1964, so any 'full sized Ford' trim rings you find during this time frame will not fit 15" wheels.
Look at Bob Drake's site, see what he lists.
I haven't checked Bob Drakes site yet but I have found trim rings listed for fitting a '56 but they don't look like what I see in the old photo of my car. I love to be able to track down the right ones if possible so I can just say the car is all original even though the trim rings had to find new ones to replace the ones missing.
~Update~
I sent a email to Bob Drake cause I checked his website and the closest trim ring I found is one he has listed as Ford Smooth 1947-48 Ford Style. It has the form fitted shape as what my photo shows and it has the ridge near the rim hub edge like shown in my photo. I asked him if the ones in my photo I posted above if they are '56 Ford or if they are some aftermarket style or what cause I do want to get the proper ones to install so once I restore the car I can display the original photos of the car in the early 60s so people can see the car then and now looking the same.
My photo again to make comparison easier.
And a photo of Bob Drake`s offering for the '47-48 Ford style beauty ring.
