The Savage Model 6 and Model 7 (tube fed and clip fed, respectively) were built from the early 30's until the early 50's. I don't have the exact dates handy, but from the stamping, I think you have a very early one.
I have a Model 6A that was given to me in 1960 by my father. He bought it in 1946,just after he returned from the South Pacific. I know it's probably not worth a lot of money, but it has great sentimental value and would never be sold. I have told my son to make sure it never leaves the family after I am gone. It doesn't have a serial number that I can find. I was wondering if someone could give me an ideal when it was made. I know the above post says 1938-1945. Is there a way to narrow that down? It is marked on top of the barrel, in front of the rear sight, "Savage Model 6A, Savage Arms Corporation, Chicopee Falls, Mass., U.S.A." It has the patent numbers stamped on the right side of the barrel and type of .22 ammunition on the left side of the barrel. It also has the large round knob type cocking handle. I have seen some that had a small shaft-type cocking knob. It has the blade and bead front sight. This old .22 has used and abused by the family, but still shoots great, even though it looks rough. The blue is gone, mostly and the stock needs to be refinished. The plastic buttplate has been missing since 1966, when a 16 year old boy (me) broke it and the stock!
I have also inherited a model 6A recently from my father. He was given the gun by his father who won the item either in the late 40's or 1950 from a punch-board. It was new when he got it and it has only been fired twice. My father had it cleaned and then stored the gun indoors in a leather case. This gun is in excellent condition.
I too have questions about the gun and as far as serial numbers, there is a group of 7 numbers on the right side of the barrel that are listed before the word "patents" so I'm thinking it might be the serial number with the number groups after the word "patents" being the patents. Because I am curious about the year of manufacture and an approximate value, I called Savage Arms Company's historian number and received a recording to write a letter to a guy and include the serial number which I'm not sure is on the gun but it was worth a shot. Here's the information.
