The .33 Win is most likely a "Lightweight" model (Not extra lightweight.) The .33 was billed as the first Winchester smokeless cartridge design of origin. The rifle was actually a pretty common rifle and many in .33 seem to be dated in the 1905-15 period. It was a good round but largely unappreciated today, likely because it was common. The rifle itself is easy to handle, naturally pointing and comfortable to fire. I have a take down/solid frame and a full mag. All are .33, because I liked the '86 but didn't want to spend what was being asked for most other chamberings selling for more. My several l I believe are two from first decade and full mag was early post WWI. Pix of my Takedown below. (Lockup on these was good & tight with adjustability feature. ) Model recommended but for the ammo problem! Best! John
