Hello everyone. I just joined today. I've been collecting military type rifles for about 5 years. Most are easy to research , but last week I bought a Model 1903 Springfield that's been sporterized and has the NRA stamp on magazine plate. barrel is dated 12-15 and serial number is 620954 ... also has the Lyman 48 sight. I found it at an estate auction here in New Hampshire .... any help is greatly appreciate ... Jeff
