Thanks guys but we've tried those sources. Along with Mr. Ulrich. What we have found out is that there were 2 such frames produced but one failed proof. After that the remaining gun fell off the radar. With a very unclear history. The pink shipping invoice shows it came from Winchester but that is about all. I won'd say what I speculate but would love to see a clear record of its journey. My best bet now is to try to trace it backwards.
