Here's one early 1950's metal promo wheel cover.   It might help complete one of your vintage promos.  I included photos of early 50's  promos to help reference it.  Feel free to contact me with any questions.  I ship worldwide.  1st Class International shipping will be calculated after close of auction, so don't pay until you ask for an invoice.  If you find a problem with the item you win, please contact me first and I'll work with you to resolve it.  Thanks for looking.
