Try the Luger & P38 forums, with good pictures. Very knowledgeable people that aren't into taking advantage of folks. Once you have a good idea, post them for sale there. Lugers in particular have taken a slide value-wise lately, though. Something to consider. If it's been refinished, has non-original parts, not in excellent condition, etc, it may not be as valuable as you think. Good photos and an eval on the forums mentioned is a start.
