While the exact maker of the engraved pistol used in the film is not definitively known, it's likely that it was a custom-made piece for the film.
Here's what we do know:
* Colt SAA: The model is a classic Colt Single Action Army, a popular choice for Westerns due to its historical significance and distinctive look.
* Engraving: The elaborate engravings are highly detailed, suggesting a skilled craftsman was involved.
* Yellow Handle: The yellow handle material is likely ivory or bone, as was common for high-end guns at the time.
Due to its custom nature, it's unlikely to find an exact replica of the pistol used in the film. However, there are many companies that offer engraved Colt SAA revolvers, so you could potentially find a very similar piece.
