I just bought an old model 41 (I think it was made in 1959, serial number 17xxx). I don't think it has been fired in 50 years, if at all. We test fired two magazines through it and it functioned perfectly. I field stripped it and saw that it was pretty dusty and the lubrication was gunned up. I decided to clean it with G96 and lube the rails with Hoppe's. Is there anything else I should do to it?
