No luck on this. They went to swap meets and after a year they trashed/scrapped or gave away until it was GONE. They said if Gary never sold it out the door they wouldn't do any better.We had a used everything emporium place in Auburn, Ne. had 2 BIG traps one looked store bought the other may have been Blacksmith made. Gary died 4 or 5 yrs ago and I Don't think they did any thing but lock the doors, I don't frequent that area unless I am going to the scrap yard to get welding iron. I will ask a few friends, but estates and family and widows can get awkward.
I talked to a guy last week that had a coilspring with teeth but it was not a full round.I am not a trapper so consider that fact when I say I was visualizing a more aggressive trap with TEETH and similar to the ones Bugs Bunny and the cartoon crew would fear monger their audience with.
If you are just wanting a trap for a "DOOR YELPER" why not take a shot at making one? The only restrictions on the imagination is your ability .
Still wondering what your budget is. I have spent a lot of time and energy searching around on this. I even paid an upgrade on my phone to talk with folks in Canada.Thanks for trying!!
