Never heard of a Winchester model 80. There is a Marlin model 80.
Winchester never made a 10rd magazine for this rifle.It was designed to hunt with and carried a 5 round magazine only.
about 1907
You may find a magazine for a 22 caliber Winchester Model 69A rifle at gun shops, online gun parts retailers, or by contacting Winchester directly for availability. Additionally, online auction sites or firearm forums could be potential resources to locate a magazine for this specific rifle model.
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.
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.
