Rocketman, I'm not a collector and not familiar with your formula. I would say the gun has been used but has no abuse, just normal little nicks and dings that one would associate with carrying it afield. Someone suggested restoration which is something I might want to explore. However, I'm reminded of an old antique bed I paid to have restored one time and was told later it would have been worth more had I not had it restored and after the fact, I was not able to sell the piece to even cover the cost of restoration.
