Fishing Weights!!!!!!

Noooooooooooooooooooooo.

No3 does indeed refer to their calibre, which is .25 (equivalent to 6.35mm).
No.1 = .177
No.2 = .22
No.3 = .25
As you state, the brand names of Kynoch, IMI (Imperial Metal Industries), and Eley are very closely linked...which is why those pellets look like Eley Wasps.
Yes they are made of lead, the way the pellets have oxidised (some of them showing a gritty white 'salt' like coating), proves that to be the case.
I would suggest they would very much be of interest to a collector, as they are quite a rare pellet/box.........AFAIR, I have never seen a box of those before.
I'll do some sniffing, and post back with more historical info about Kynoch, IMI, and Eley....hopefully so we can pin a (roughish) date on them.

Thanks for showing us Tom.........and welcome to Planet Airgun..........and PLEASE don't melt 'em down just to dangle in the water!!!!!
