I have a three barrel shotgun/rifle that I would like to know more about. It has nimrod gewher fabrik on one barrel & thieme & schlegelmich Suhl on the other. It is hammerless. There are some numbers on the barrel 2g Sch.P. over 27gBL. also looks like a crown over N . Under the stock on the barrel is 2.7gG.B.P over St.m.G. Maybe a serial number 32381. Another number 1220. It has nimrod patent on two flats under the barrels. It has a door on the bottom of the stock with 4 holes for bullets. I think it is 2 16 ga shotguns on top & a 72 x 9.3 mm rifle on bottom. Any info on how old it is or value would be great. Thanks
