Going on the idea that there's a missing number, and that the 8 87 is an expiration date, (Narrows it down a bit, if football helmets are like bicycle helmets they're supposed to be replaced after 3 years. ) I went looking for pictures using the pro football reference uniform number search. Interesting that there are so many 80's guys where you can't find a pic online... (Also true of cyclists, but that's more of a fringe sport especially back then)
I found a couple possibilities.
33 Curtis Dickey - Used Bike, but no pics show that facemask
43 Frank Middleton - Used Bike, and at least for a while, that facemask. The pics I found are all from angles where I can't see the chinstrap clearly.
There's way too many guys who played during the right years to say for sure, but Middleton looks promising.
