Model 70 Serial Number Question?

Recommended Posts

I'm trying to date a Winchester mod 70.

Cal is 375 H&H. It does have the mauser type "claw extractor".

At present it has a synthetic stock.

Serial number is Gxxxxx . That's capital letter "G" followed by 5 numerals.

From what I've found out the letter G prefix started in 1968 at around 700,000

This rifle is G96,xxx ? :huh:

I know that at some point (1990's) winchester went back to the claw extractor.

Is there something that will tell me right off that this is an actual pre or post 64?

I dunno. I just looked at my M70. It was made in 1965 according to the PDF from Winchester. There is no "G" proceeding the serial number. According to the PDF, the "G's" started in 1969. When they restarted producing the ones with the claw extractor, I don't know what they did with the serial numbers. The G would kinda indicate a later production to me, but I am certainly no expert.

As Dr. H stated. Production of "G" prefix md 70's began in 1969.

 

The last md 70 produced by yr end 1970 was G957995. Last rifle produced by yr end 1971 was G1018991.

 

By this reckoning your rifle was produced in early 1971.

 

Reference matl. was BB of gun values Winchester serialization section.

 

JM2c.........hope that narrows your search.

Part of the mystery is solved! I was able to take another quick look at the m-70 today.

On the right side of barrel (go figure ;) ) it says "classic sm" (synthetic matte) The bolt has a small gas blocker attached to the extractor ring that is behind the the left locking lug when the bolt is opened.

 

The 5 digit serial number with G prefix is still unsolved though.

Sorry Dude,

 

The 5 digit serial number with G prefix is still unsolved though.

 

Until you put in written words that it was a 5 digit ser # I brainfarted and thought it was a six digit by simply looking at first 3 numbers.

 

Last 5 digit #'s were in 1948 without a letter prefix. Certainly no synthetic stocks made then.

 

The mystery continues.

 

I would contact Winchester or a local Winchester factory authorized service center.

It sounds like your gun is not a pre-64. It is rather a "Classic" produced after the pushfeed guns. I have a Classic in the safe right now for rebarreling to a 284 with a long throat. They are good guns, just not hand fitted like the pre-64's.
