These jars date from the 1910's and 1920's and have no relation to Lewis Boyd. The only source that I know of today where these rings can be found is at or you can get boxes of the old gaskets on e Bay.It is very difficult to determine the age of a fruit jar without seeing it.

Jars carrying this embossing, often with other monograms, numbers, letters, etc., were widely produced until about 1920. The identities of many actual manufacturers are unknown.Lewis Boyd filed a patent in 1869 for "an improved mode of preventing corrosion in metallic caps" i.e. This innovation kept food from coming in contact with the zinc in the screw caps.Boyd was actually one of three men who gained control of the patent for screw caps and jars originally filed by John L. "Boyd's Porcelain Lined Caps" or zinc screw lids for mason jars were made well into the 20th century (at least the 1950s) and were interchangeable with the millions of mason jars made by hundreds of different manufacturers.However, I have never found any concrete evidence to back up this claim.Lately, these jars have sold for more on on-line auctions such as e Bay.
