Anyone heard of Kings Choice?

[Gobig_or_Gohome_toms]

My mother in law is a master gardener and one of her master gardener friends has been growing this tomato for many years and saving seeds but sowed all his seeds in a bad mixture last year and none germinated and he is tying to locate some seeds. The info I got was it was the name of the tomato is KINGS CHOICE that was developed and sold by Northrup King.

Any help would be appreciated.
