Were these guns just the proverbial "flash in the pan" or are they still available?
Had one offered to me, but in the lower grade, without the case hardened receiver and lower grade wood. Tried to find something more to assess value and there is not a bunch out on the net that is up to date!
Are they discontinued, or still available and where?

They show up on gunbroker sometimes. I am very happy with the one I got on an early custom order but I don't know that I would buy another random one.
