Tho the breed is visually black and white, the Delaware is an eb (Brown) locus based Columbian breed with the barring gene. Unlike the eWh locus-based Light Sussex and Colombian Marans. In an eb based fowl, the under fluff is a tinted hue. The top color (white) is balanced by choosing the right hue in the undercolor. In eb based breeds, if the under fluff is not balanced correctly. black stippling shows up in the feathers on the saddle and back. It is possible that the spotting you remember in the Ohio Beauties is a deliberate misbalancing of the underfluff on a Delaware which resulted in numerous and heavier spotting ( called stippling) on the white parts. I would ask Glenn Drowns about this.... or if he thinks the Ohio Beauty is a "splash" type breed which is made by mixing 2 solid color birds ( in this case, black bird and white bird), different genetics. If Glenn knows the original mix used to create the Ohio Beauty, that will tell the genetic tale.
Best,

P.S. in eWh locus based Columbian breeds which are black and white, the undercolor is white to the skin. No color balancing needed to establish correct white top color. No black colored stippling in the saddle or feathering in the back... unless the black color in the hackle and tail is has too much black and it causes black leaking out in the feathers of the saddle and the back. This black leaking in a black and white eWh based Columbian breed is a fault in the eyes of the Standard.
