Hi Dave, I look forward to seeing photos and shooting report for your new 1860.
I have sold firearm items on GB a number of times. Sometimes the buyer doesn't understand how to use the items I sold them where hand-holding is required. I always offered to accept returns and pay the return postage. I never had anything returned. I always prefer to buy from forum members before going to GB because I am aware of GB seller exaggerations. I once purchased an 1863 Remington with a Kirst .32 S&W conversion cylinder on GB. When having issues with the conversion cylinder, the seller told me it worked perfectly for him. However, a call to Kirst suggested that that .32 S&W conversion cylinder never worked reliability and offered to replace the cylinder with a newer version. I would have demanded a return and refund, but decided to keep the revolver with conversion cylinder since the cylinder is no longer made and is now a kirst collectable. I have seen many GB offerings where the seller had no idea of what they were selling.
Regards,
Richard
