"White" and "Laydie" were the two men who designed this type of open back tone ring. These banjos came in three sizes - this one has an 11 inch head.
This is an excellent conversion of the 1927 original using the original neck serial number 76424 It has the original skin head and case.
Looking around the internet I find spellings of White, Whyte and Laydie, Ladye, Ladie and Lady. .Once you buy it, you can spell it however you like.
