If a .22 magnum cartridge fits the cylinder you have the .22 magnum version. The .22 LR and .22 magnum cylinders are interchangeable and if your barrel is marked for ".22 caliber" it should handle both LR and magnum cartridges. If a barrel is specifically marked for ".22S, L, LR" or ".22LR" it may not handle the magnum cartridge or accuracy could suffer. The ejector was used for all models and I am not sure why it would have been removed unless it was broken.
