If this is a low-wall rifle and the cartridge is said to be a .32 Winchester, it will most likely be a .32 W. C. F. (.32-20).

Other .32 caliber chamberings include the .32 Short, .32 Long, .32 Extra Long, .32 Ideal (.32-25-150), .32-40 and .32 Win. Special.

If factory original, I would expect the to see the .32-40 and .32 Win. Special chamberings only in the high wall configuration.
