If you are looking for information on the quality of these guns I can tell you that overall reliability is not great. That being said there certainly are many people who have owned these guns without any problems. However, when classic doubles went bankrupt I worked on many of these guns with various problems (I'm assuming that these where problems that would have gone back to the factory had they not gone bankrupt). Also, I took part in building a few of these guns from some of the Galazan parts kits (leftovers from Classic Doubles) so I am well acquainted with these guns. With this experience I believe that the final product did no live up to Classic Doubles advertising hype. Truth be told I saw a rather narrow segment of the Ithaca classic double guns that where produced, dealing mainly with understandably annoyed people and problem guns. However, some of these guns are nicely fit and finished while others are not. If you find a good example at the right price buy it especially if it has been shot moderately and proven reliable. Just make sure it is selling for a good price.
