I haven't got a micrometer and to be fair, the old Duffus has suffered a bit of corrosion on the wires but I'd wager that the loops on the modern S/S Flatpacks are a tad thicker and of a harder temper than the Duffus. I form this opinion based on filing the burrs off the trigger latches and bending the trigger wires. On a FP I have to use pliers to hold the top of the loop while I push the bottom of the loop forward. And it is a hard push. With the old trap I can do it just using my thumbs. I'm only talking about the stainless wires on the FP. I found the regular version of the FP traps had more malleable loops though so S/S is the way to go and squeeze the bodies in.
The version I mentioned earlier with the stronger body is also smoother to set than the other types of FP traps. With the S/S versions of FP traps I would tune them so they were like Arkwright's till and sometimes they would go off when placing them, but I put up with that. After a couple of weeks they settled down and after a month or so I tuned them again and that was that. they never needed touching again. And I didn't have to do that little trick with the triggers after placing the traps either.
I'm driving over in Oct / Nov and might just pop over to Skipton with the versions of S/S taps and ask them about them. I know I'm only small fry but they advertise sets of three traps and so should be geared up for us Mickey Mouse outfits.
That's interesting Nicepix
To be fair, I've never actually seen one of the stainless versions up close and personal; as I posted earlier, the problems I had with my original batch of Flatpacks put me off ordering any more
I'd ask, nay beg, anyone reading this with an interest in the subject to get hold of Flatpack ASAP and ask them to read what's been written here
Here's a link to their contact page
I still believe the half barrel trap, overall, is the best 'design' of mole trap, but the only way the manufacturers might address,concerns, is if sales of the trap started to plummet ? However, i know this isnt going to happen,because theres alot of reliance,on this type.The challenge for me now, is to carry on without them,.....cause i could be doing with a good number of new ones, but i refuse to buy anymore,the way things are ? The last new traps i had, were a small number of "bethels", from a member on here, who very kindly,sent me them.I tried to adjust the 'loops' on one,with pliers, and the wire snapped !! ,.....never had that before (with a new trap),so that was the last straw !,.....lol Virtually, all my old stock, arent fit for purpose,anymore,......ha ha
