I found my first silver last weekend in a park about 15 miles away using my new to me Gamma 6000 @ about 6 inches. A 42D Merc. It was my first outing with both my Gamma and Omega. I must say that I am impressed with both machines. I know that cleaning is a NoNo, but I just couldn't help it with this Merc. I could see that there was a lot of detail beneath the swirling tarnish that covered her, so I used some Eagle One polish to take that off. Wow, am I ever happy! I will, most likely, never get rid of her, so I don't care that she has been cleaned. Here she is . . . Oh yeah, her younger brother ain't bad either (53 Rosie)!
