Dalrymple Bishop and Stonier Bisto England ceramic/porcelan set blue and white

I have a set of Dalrymple Bishop and Stonier Bisto England ceramic/porcelain blue and white, 11 large plates, 12 small plates [1 small plate has some discoloration from house fire] 1 large platter and 1 small platter [large platter has a couple very small black spots from fire] 1 large soup turren with feet, lid and ladle [ladle handle is cracked], 2 vegetable dishes without feet and 1 interchangeable lid. 1 gravy boat with cracked handle. Soup turrens and plates are all mint. No chips or cracks {except 1 small one I mentioned before} The plates have a "c" marked on them and soup turrens have a "10" imprinted in them.

I have endlessly looked on internet, gone to the library and looked at books, etc. and have found nothing on Dalrymple. I am very curious to find out what I have.
