Comments from Submitter:
I have carefully studied the instructions for this set, and disassembled a built version, and believe that these are the correct quantities for these 2 pieces. Other websites (Brickset.com/Rebrickable.com/Peeron.com) also list these quantities, with the caveat that 1 of the originally 2 1x6 red plates may have been provided as an extra. I can't confirm that, but I can only find 1 in the instructions & build)
