Also quite a few Mustad 7691, Southern Tuna Hooks. I used those at Guadalupe in August. Save the chafing rings and grommets too, if you toss the mono and wire leaders. The stuff is probably over 15-20 years old, but a lot can still be used and save you money. The 7691's will set you back a few dollars apiece now days.
That box may have been a good find, depending on what else is in it and what condition (is it usable?) it is in.
take a couple of the leaders and uncoil them, see if they will straighten out. If so pull on them to see if the mono will hold up. You can always rig something up with a come-a-long to put some oommpphh to it without puuting yourself in harms way.
Funny, I scored an old, wooden box that had those same 3997 hooks in it. They worked well for dropper loop fishing at Guadalupe last year.
I'm no 'crimping' pro, but I wouldn't trust the ones pictured. They look to have been literally crimped instead of swaged.
