Parashooter,
Things are definitely better than 40 years ago trying to find parts. I sent a check out and got something that looked real ugly. I did not even try to fit the thing. Long distance calls back then were high and who knew where to call. That trigger plus the broken one are still around here, I will post a photo when I run across them again.
I am with you on wanting the long pull on the first stage, I did modify mine to make the second stage shorter and I still like that all these years later. I can not tell if the Huber trigger would let you do that or not. From the photo the workmanship looks fair, as far as the shape and general machining. It looks like the paint or Teflon coating ran a bit though.
