Reading about "Green ripe" vs "green flesh" this evening. Green ripe is an ethylene sensitivity mutation, and is associated with delayed ripening - so Black Early must be a gf allele, not Gr - it is very early ripening certainly not delayed.
This is about Green ripe:

Also found this abstract of a Russian research paper on interactions of gf and Beta.

Abstract
Results of investigation on non-allelic interaction of mutant genes gf and B in tomato are represented. It was revealed that gf gene inhibits beta-carotene synthesis owing to incomplete transformation of chlorophyll. In a double BBgfgf homozygote the joint discrete manifestation of effects of two genes takes place resulting in a new phenotype--dirty-orange colour of a fruit."
Something to look forward to..
