This is a 1952 Olds Mendez Bb trumpet, which was the first year of production. The Mendez was created for trumpet virtuoso Rafael Mendez and modeled loosely after his French Besson. The Mendez model has unique braces to all other Olds models and has accents reminiscent of French trumpets of the day. It has first and third valve slide triggers.
This particular Mendez has a very low serial number. There is only one Mendez trumpet listed on the Olds Register with a lower number, so this was likely made in the first batch to every come out of the Los Angeles Olds plant. Many of these early Mendez models were gold plated. This trumpet has been refinished with gold plating in the past, so perhaps it was originally gold plated which prompted the replating also in gold. There is minimal wear to the plating as shown in the photos.
The gold plated finish gives this horn a stunning appearance. The valves do not appear to have been replated when the horn was restored. Valve compression is still good. All parts appear to be original, with the exception of the pinky ring mounted on the leadpipe. The style looks appropriate for the horn, but it is not the original pinky hook. Does not come with a case or a mouthpiece.
