3 3M SCOTCH 206-806-809 [sealed] 1/4" Audio Recording Tape METAL REELS

I AM IDENTIFYING THE MODEL OF TAPE FROM CLUES. ONE REEL HAD 806 ON IT. ONE WAS NOT MARKED ON THE REEL BUT THE BOX SAID 250. ONE  809 IS STILL SEALED IN PLASTIC BAG.   I AM PRICING THESE AT  THE COST OF EMPTY REELS SO CONSIDER THE TAPE ITSELF FREE. BE SURE TO SEE MY OTHER METAL REELS. THERE WILL BE ONE SHIPPING CHARGE OF $7.95 HOWEVER MANY REELS YOU BUY INCLUDING ALL THE LISTINGS.
