These are being sold for collectibility purposes only if you choose to wear themyou are doing so at your own risk. I made no attempt to try to clean them as I did not want to disturb the vintage patina. Not sure who these were made by but if you know, I would be very interesting in learning more about them not sure exactly how old they are but I do do believe they’re from the 50s or the 60s. if you have any further information, please let me know if you are unable to pay for them promptly when auction ends, please refrain from bidding. Being sold as is condition for collectibility purposes, only the show plenty of stains spots, marks, discoloration, scuffs, scratches, etc. etc..
