I have a model 1898 that I inherited from my father. It has been in the family since a great, great, grandpa was in the Spanish American war. We have letters that he wrote when he was in the war. It has a cartouche "1899". From my research I think it is a rifle. Serial number 315091. It looks all original.  The sight looks like the example you have for a 1901 rifle. Any help would be great. I want to know when the gun was made, in service, what it may be worth, how to care for it?
