I have never seen TGFOP GFOP FOP grade single estate darjeeling
teas.(even if some darjeeling tea is very cheap)

Tea garden do grade all darjeeling whole leaf as FTGFOP(1) or
SFTGFOP1?

Most single estate DJs that find their way to western shores are of
better qualities, usually FTG.. or SFT..., whereas most of the lower
grades (down to dust) end up in blends or teabags, usually sold without
grading. There are however noteworthy exceptions, Gopaldhara´s
excellent Oolongs (e.g. "Red Thunder") are sometimes sold as FOP
(different plucking system) and once in a blue moon I´m partial to Mim
Tea´s GFOP, a nice strong breakfast tea.

Nope, they grade their teas as whatever comes to their minds (and bears
some similarity), then once in a while some vendors add their 2 cents
and do a little upgrading. The "1" means "a little better" but not
quite up to the next higher grade.

Just google for Darjeeling and TGFOP, GFOP, FOP, BOP or whatever and
enjoy the results.
BTW: I never heard of Castleton Muscatel Broken Pekoe. Anyone ?

Thank you for kind reply. Your reply is better than other tea
books.(they only say FTGFOP1 is Fine Tippy......., OP is Orange
Pekoe...)

I have also never seen Castleton Muscatel TGBOP.
