Cagunman, no apology necessary. It is a very common mistake and thus gets spread easily.
If you do get in touch with Chris Dawe, you should know he has a special place in his heart for Lefevers. (As do most serious aficionados of North American SxS shotguns). Dan Lefever is recognized as perhaps the most inventive shotgun designer working in America during the golden era of SxS shotgun manufacturing. If you have received his contact info from Brian (gunsaholic) you should call Chris and discuss the gun and required work with him. I know Chris will be able to give you a lot of good info that will help you decide whether to pull the trigger on the deal or not.
If you don't have the contact info yet, let me know and I'll pm it to you this morning. I'm just packing up a gun to send to Chris this week. Chris is based in Newfoundland and it's likely he will be hunting this weekend, so try to contact him today rather than the weekend.
