Winchester never made a 10rd magazine for this rifle.It was designed to hunt with and carried a 5 round magazine only.
Maybe ammo clip.com,or Numrich gun parts corp.as far as I know these winchester model 88 rifles which were made to hunt with came with only a 5 round magazine from the factory.If you find one it will most likely be a after market made magazine.
well just put in the model number and the part you are looking for in Google and then just shop something like: Winchester model 69 A magazine assembly
Ammoclip.com for a new reproduction magazine. You can find the factory magazines on Gunbroker.com.
Never heard of a Winchester model 80. There is a Marlin model 80.
Sarco has them in stock there part # Misc119
I would look at numrich gun parts corp.They can be found on the net.
Try Numrich Arms, they have a website and a lot of used and new parts.
