The chambering will be stamped into the barrel next to or under the Winchester name.Model 1890's all had .22 caliber barrels, but they could be chambered in short, long, and long rifle (LR).You might even find one in .22 WRF (The fore runner of .22 magnum.)If there is no chambering stamped in the barrel, or it only says .22, it's chambered for the .22 short.The reason being that it was made before .22 longs and LRs were commercially available.
There is no such thing as a 22 magnum caliber. There is a 22 caliber, which means that the diameter of the gun barrel is 22/100 of an inch in diameter. The magnum has to do with the powder load in the shell holding the bullet. It is slightly more powerful than the smaller size shell. A 32 caliber has a larger diameter barrel. With 32 caliber, you do not usually have much choice in the power of the shell. If you want to learn to shoot, it is a lot less expensive to shoot up a lot of 22 ammunition than 32 ammunition. If you want personal protection, a 22 is next to useless. A 32 is not much better. You need at least a 38. Better is relative. It depends on why you want a pistol.
On the barrel of most guns produced, the proper caliber/gauge is stamped as well as size/ type. That being said I think the model 16 was a semi-auto .22 caliber, firing a .22 caliber long rifle round.
