The 2oz & 4oz trolling sinkers I have came from Crawdads Fishing Tackle .... the 1oz trolling sinkers I have came from Cabelas (local store). All three are the torpedo shaped sinker with line tie rings on each end ... no swivel ... but, Crawdads does have some made with a swivel on both ends (black crane swivel) ( Trolling Sinker Weights
– Crawdads Fishing Tackle )
Just FYI
Snagged some off ebay but next time I will go with Sinkermaker. Thanks for all the help
