are you certain as to that "prefix"???? last we could tell, that the number 87 was used for the Super Blackhawks.............
1979-80 the Super Single six used a number 67 prefix, and those would have been the yellow,black end ,one piece fold up boxes with a red colored end label.
the prefix number of 67 is about near or into the change of boxes from the one piece,fold up red/white boxes they used from when the "new models" came out and your number is near the change to the one piece yellow, with a black end and came in a brown cardboard shipping sleeve ( so did the red/white ones)...........
we'll have to dig around the stash here,not many left these days..........
