i have two "B" sprues, although one set of "B" parts is identified as "b" in the instructions.
the "F" and "I" (i think) sprues are molded as one sprue.
and the parts are on the sprue in no real apparent order.
the instructions are vague as far as parts placement (fender support)
direction of piece (hatch hinges)
on my 1/72 Tiger, they left a piece out of the instructions and drew it as if it were molded on!
but i am still having fun.
