I love these old guns! I've seen VG-EX examples go for as high as $550 and fair to good cond with homemade checkering as low as $185. Nice glossy finish on wood with bright blueing and VG bore should get you around $400 even with a minor scuff or ding. From your pick, I see some faded blueing and a dull finish with some dings. If the bore is shiny, and there's no rust freckling, I would feel comfortable offering $285-300 max. In the end a gun is worth exactly as much as somebody is willing to pay. Hope this helped.
