anyone here know how they labeled the helmets; either with dymo tape on front with player name or uniform number on back? i recently bought one and i date it to the 89-91 period and has the #30 on back.

devon white wore #30, 89-90. he wore a lefty helmet when batting. maybe used a flapless for bp?
ruben amaro jr #30, 91. again, maybe worn by him for bp? perhaps worn in minor league play?

there is an older one on ebay worn by reggie jackson that has the tape on front.
