To give a good estimate of a gun one has to have it in hand as Bill has said. Another point to consider is that prices vary from country to country depends on the availability. I agree with Billâ??s estimate, but on the other hand, a gun like yours would bring a bit better price in my country.
Regarding this forum what I can say is that I learned a lot and made some good friends, so hang on, because it is gold mine of information.
