Hi Frank,
Your not looking in the right places, your not limited to Oregon, we have the internet now

, makes things a lot faster and easier, try Gun Broker or Auction Arms, not long ago I bought a real nice Ruger # 1 from a long time ASSRA member for $ 525., it was in a useless caliber, 300 Win Mag, but I was changing the barrel any way. I own a few # 1's, and never paid more that $ 575. for any of them.
As to lock time, well I don't think your $ 20. spring and a file job will come close to being as fast as one of the Frank Zika speed hammers and the speed spring that comes with it. Or if you think a faster lock time than that well help the sear notch can be re-cut a 1/4 inch closer by a good gunsmith, now you not only have a lighter hammer you also have one that does not have to travel as far to the firing pin so it becomes even faster.
It's all about the mass weight, if you ever get a chance weight a High Wall hammer then weight one of Franks speed hammers, I think you will find that in order to get that mass weight of the Wall hammer moving it will take a very big spring, so big that you may have a hard time cocking the hammer. I'm not totally sure about all of this but this is what I've been told by a few gunsmiths.
Yes, a striker breech block would be nice and faster, but like you said it's probably not needed on a bench gun and I don't know any shooters that can say that a striker breech block made them a better OH shot.
Frank,
You said that "It also makes the # 1 just a straight bench gun and not a combo BR/OH rifle. Lock time isn't as important on bench guns as it in OH"
How does all this make the # 1 just a bench gun ? you can get very fast lock time and put any weight barrel on the # 1 up to 1.200 and with very little work you can go to 1.250, that's more than heavy enough for any OH rifle that I would want to try an shoot.
What we need to do is find out what Joe B's problem was then maybe some of us can help him out.
