I would consider a trade. Do most of these spinners not have the "saltwater proof" sticker ? I thought it was kind of odd. The reel was purchased here in BC on the West Coast so maybe they added that for this market ?

The early ones all came with that decal on the rotor. They're not really "Saltwater Proof" but they are fairly Saltwater Resistant. They still need to be regularly rinsed and cleaned, and they will show the normal saltwater affects if neglected. The metal bail plate was a special saltwater feature that only came on that version. They are really nice reels for heavy freshwater or light saltwater.
The "6" is probably the least valuable of the 3, 4, 6 & 7, and not at all rare. In the condition yours is in it would probably bring $35-$45 unless it has the original box, pamphlet, extra spool and tool. Double + if you have those extras.
