Wow, that's a beauty.
I would think it had its own paperwork if it's new enough to have had the instruction sheet / parts list. The Model 37 had its own when they started adding them (I don't know when that was -- maybe one of the other folks knows).
The only one I'm aware of that didn't have model-specific paperwork was the Chiefs Special Target Model 50. You got a Model 36 parts list in the box with the Model 50.
