Hard to tell from just that one picture, could be G&H, but I would say they are old Flambeau magnum mallard decoys. Would need to see the hens to be sure. We use to have tons of them. Nice dekes. They are worth what someone is willing to pay. If you were closer I would offer you $40 for all of them. I have a soft spot for them, but in todays market new decoys are relatively cheap. Those decoys themselves hold up well, but would need to be painted. That takes time and money. When those decoys were in production it was very common to rig them with the scoop or bucket type anchors. You would wind the last bit of line around the neck and then fit the anchor over the bill. At least the vast magority of the ones I have seen were rigged that way. Not worth much money but a good find though!
