I put this together some time ago from comments and pics posted by Dave on several forums and threads, without his permission or encouragement http://www.picturetrail.com/sfx/album/view/22641451

He hasn't sued me yet SO I'd like to add pics of different grade guns or Tobin advertisments for reference when questions arise. Post here or send by jpg attachment to revdoc2@cox.net and thanks. As previously stated, this is not a commercial website.
