I think you can do better on a shooter, Randy. Have you checked Lefever Arms Collectors site piggybacking on the PGCA site? Useful discussions there which would give you a basic familiarization with what others are thinking/looking for. If you must have a time capsule gun, you probably should expect to pay the fare. You might also want to get Elliott's Lefever book.
I'm wondering why there isn't a price structure tied to variation in the mechanism? Perhaps there is. I'd like to have an earlier Lefever with All the adjustment screws as recently described by Silvers and 2-piper.
