DBADCRAIG......I'm sure one of the resident'Scanners' on mr Webers World Renown Webers Warriors Web Site" Has already Noted the Overall Condition of the Well Used Put Away Wet , Many times.Greener.. Shotgun. The English, (Pardon me,Its getting close to St. George's Day)..used to have a coin called a "Farthing", When put on the backside if a "Leg-Vise" and struck repeatedly with a 1 lb.Hammer ,could be flattened down to the Victorian equivalent of a Modern"RCH"..It could be used as a Gauge'for checking the Barrels on Face'.. I would suggest that you shut the Barrels down onto a "Feeler-Gauge'Maybe a 'Couple of Thou"(Our Hammered out Farthing was .003") Your gun has the appearance of being "Off the Face", It should be a 'Water-tight' fit. (Or as "OLD 91yr old when I was 15. Arthur Wilks.Purdey Owners check your left Bbl on the underside for the Initials of the Bbl. maker,,'AW')...used to say, when Barrels fit the action, "Hot pee wont get out if you poured it down the tubes.... In all seriousness, Something looks 'Amiss at the breech-end! Have your'Man' check it out. Remember, Off The Face is just That! No gun is built with Barrels "Off Face"..We have a collection of Greeners from Muzzle Loaders to Modern Hammerless'All are 'On Face". Its easy to get caught up in the 'Romance of thr Gun" Just make shure the gun is safe to shoot Modern Shells" I 've had 3 customers in the last 12 mths.Loose 'Bits" from their left hand....Be Safe..CC/dt
