I happen to have a Milazzo-Krieger trigger, still in original packaging, that I will probably never use, so I'm thinking about selling it. There seem to be mixed opinions as to what it is worth, or rather, what I should ask for it. Suggestions will be much appreciated. And on a similar subject, I also have a Creighton Audette case measuring instrument that I'm also not using. Photo attached. Suggestions? Merry Christmas Everyone
