I found the value of a Marlin/Glenfield (similar serial) to be at about $2,700. I'm looking too, but that's the price I was able to find.
Marlin made the Glenfield firearms, not Winchester.
The AB prefix to your serial number indicates that your glenfield was made by the marlin firearms company in 1966.
The Glenfield MOD. 60 (.22 cal L.R.) by Marlin Firearms Co. is a semi-automatic.
Try Gun Broker, Auction Arms, Guns America... you could post some "WTB" (Want to Buy) topics in any firearms related forum you might post on.
Glenfield,which was made by Marlin Firearms Company made a bolt action .410ga shotgun from 1956-1965.This was the marlin model 59 which is the same shotgun as your Glenfield model 60.
Glenfield firearms were manufactured by Marlin (many were marked with both names). Cotter & Co was one of the retail hardware stores that sold Glenfield guns and some of them were stamped with the store name.
Firearms were not required by law to have serial numbers until Congress passed the gun control act of 1968.Begining in 1969 all firearms were required to have serial numbers.Chances are that your Glenfield model 70 does not have a serial number.
It would have to be older than the implementation of the Gun Control Act of 1968, which mandated that all cartridge firearms have a serial number.
where is the "best priced" shop to purchase the loading tube for the golden 50 glenfield 65 22 l.r. by Marlin Firearms?
The Glenfield brand is part of Marlin firearms. The most definitive answer will come from Marlin. And the nice folks at Marlin Customer Service just told me that your rifle was made in March of 1972. As far as value, depends on condition. In Excellent condition, these currently sell for between $375-$400. The 30A is a slightly plainer version of the Marlin 336- an excellent rifle.

The Glenfield model 75C is a carbine variant of the Marlin model 60 produced for 1975 to 1992 by th m Mrlin Firearms Company under the name of Glenfield. Differences include shorter 18 inch barrel compared to the Marlin's 20. Length of pull on the Glenfield is shorter. The Glenfield also has a shorter and lower capacity magazine tube. The Glenfield hold 9 shots in the magazine, while current Marlins hold 15. Nearly all parts are interchangeable, and the Glenfield can be converted to modern full sized Marlin 60 specifications if desired.
