Michael, thanks for your help. I apreciate you taking the time to help my less learned self. According to the list, my Cornwalls were born in '75'. The serial numbers are hand written in ink, they are 6N334 and 6N335. Do those numbers sound legit. The tag on the back is pretty faded so it is hard to read anything else like the name of the person that tested them, inspected them, or the type. Do you have any suggestion s on how I might research these things?
Again, Thank you
(P. S. yes I was born in '57')
