Bristol Blenheim questions

[Dak21]

Looking at the unofficial stats for the Bristol Blenheim, and the deck called for is J(b). What does the "(b)" indicate?

It probably means there are no reversals (Immelmann turns) or fast sideslips.

Looking at the unofficial stats for the Bristol Blenheim, and the deck called for is J(b). What does the "(b)" indicate?

From the notes file:

Any deck with the modifier (b) is for bombers: no reversals, 45 degree turns, 60 degree turns or extreme side slips.
