Dave:
You can contact me either way. I'd recommend a call first. Then, if you need me to provide an opinion for an item you are considering to purchase, you'll need to provide images and info (or a link) for an Online Opinion, or ship me the pistol for an actual in-hand inspection. But we can talk about all that if/when you call or e-mail. Thanks for signing up at the site. Hopefully, it will prove to be a valuable tool for you in authenticating pistols. Good luck.
