Hello, I am new to this forum and to guns in general. I just purchased a H & R SINGLE SHOT SHOTGUN, 16 GA., SN 196801, with a pat. date Feb 27, 1900. From other answers I have read on this forum, especially by b.goforth, I understand that the 1900 is the model #, not the date of manufacture. Is there any way of telling what yr it was made by the SN 196801. I also assume it should not be fired, due to its age, even though the condition is good. Am I correct. Also, what type of license, if any, should I have to own this and any other antique guns I may purchase later. Thank you for any responses.
