In point of fact there WERE cartridges advertised as ".45 Long Colt", in the late 19th or early 20th Centuries. While I can't locate the photos of the boxes, I have seen them. IIRC, this came about when the double-action swingout cylinders came about. The original rims on the .45 Colt's were too narrow to catch the star ejector, and the ammo companies enlarged them, and began advertising them as ".45 Long Colt". There "never was" a cartridge called ".45 Schofield" either. The correct term was ".45 Revolver Ball". It was intended to fit either the Colt's Single Action Army revolver or the Schofield. The terms ".45 Long Colt" and ".45 Schofield" are modern-day appelations intended to avoid confusion. The term "pistol" is now generally used to describe a semi-automatic handgun. In the Old Days, the term for a gun with a revolving cylinder was "revolving pistol". Likewise, when it comes to terminology to describe different variations of a basic gun, we use modern terms like, "Second generation Colt". But, I doubt that Colt's uses that term. Likewise, I doubt Winchester has officially differentiated between a "Pre-64 Model 70 and "Post-64" rifles. Just modern conveniences.
Now, you may flame when you are ready, folks!
