Thanks to all of you for the information and quick replies!
This will be my 6th season growing heirlooms, and I never knew how much interest and knowledge of the art existed until John turned me on to this site last year.
I grew a Burpees so-called Red Brandywine last year, but it was a potato leaf...last year's weather was disastrous, so I can't report on the fruit...not one was produced.
