Here's a pic from the eBay listing. Selling for 125 a dozen by Dakota Line. I I can't find them on Dakota Line's website though. As you can see, there is one oddball trap amongst the dozen pictured, and also an end swivel on backwards. They appear to be zinc coated, but there is quite a bit of rust showing. This the first I have even been aware of their existence, but from the eBay listings they look to be questionable quality wise.
