I used them years ago on Coldwater and Castle Lakes up by Mt. St. Helens. I rigged them up with a single barbless hook due to restrictions on these lakes at the time. Skunked in 4hrs at Coldwater but caught 3 in Castle in a couple hours if I remember correctly. Cast them out from the bank.
I still have the two lures (brass and chrome) and don't know who made them. Hadn't been used unless I come across these restrictions again.
