For a left handed vintage Strat, this is as rare as it gets! This is a factory original Left Handed 1964 Fender Strat in the ultra rare custom color finish: Red Sparkle. It is also known as Metallic Red, and the abbreviation of “MR” along with LH for Left Handed can be seen in the top of the body. The letters are in a style that is typically seen on custom color finishes done by the Fender factory.
This is a color that Fender rarely used, and is not even seen in the Fender factory finish literature. Most likely it was a color used for promotional purposes, such as the NAMM show. So it is more rare than even the rarest custom colors!
