Who makes this trigger spring?

My dealer had several of them but no info on them. I have installed them all and can get 13 to 16oz triggers on my NM's with them. They are a relatively thin wire that hangs from the pin rather than slip over it.

Thanks

Lee's gun smithing still shows a similar spring. Someone else was making them and I had a set long ago but I can't remember who made them.

Trapper Gun springs, Natchez carries them, I have a bunch and like them better than the trigger springs from Wolff.
