Your gun is probably older than mine. Look at the spread between the numbers stamped in the forend wood. About 6000. If that represents the number of guns made between them that is quite a bit. It is possible that the 6000 guns were not all the same type of gun. There could have been rifles and single barrels mixed in that number. Could you post a close up picture of the horn forend tip Please? Mine is missing but the inletted area is shaped like yours. This will help me when I get around to restoring mine. Is the checkering the same on your stock as on mine? Read all of my R Grove post and you will see why my gun was likely made by Midland and possibly yours also.
