Reason I asked,I have used about every #1 stoploss ever made.I bought several dozen #1 1/2 Northwoods stoploss,which I thought was modeled after the B and L #1 1/2.
I got rid of the whole bunch,the stoploss spring actually went over smaller rats and female mink without touching them.Alright for the larger ones but worthless on smaller ones.
All my stoploss,are and have been #1s ever since.
