Well look at it this way,..If I put a drum up for sale and it had four mount holes that I put there and the rail was missing, I couldn`t say it is original, or sell it as original because it would be by definition a players drum.
If I sold a drum that had four mounting holes that came from the factory that way and put the original missing part, or an era/time correct one back on, or sold it with the missing part, I could still say it is original and not a players drum.
Now the drum is advertised as one rail and the one with two makes it special ordered...but original and not players....Right ??
