In response to Thomas Altmann & Coco,
Thomas, am Dario from the Latin Jazz group, the one with the discussion regarding Mongo and technique. I play both bongos and congas and timbales but on rare occasions. Lately mostly congas, whenever there are gigs, Miami surprisingly is not like NYC or LA. A couple of years back I used to play a lot of bongo' with a Cuban sextet that featured guitar ,tresero and two trompets, but that ended.
Coco, Those shells are about 50 yrs. old solid Caoba. I also have Mongo's Vergaras, Mongo bought his in 1954 when he played with Tito Puente and he bought them for Willie Bobo, Tito's bongocero at the time. Mongo's Vergara are 7" & 9", he had Vergara make the hembra oversized. Mongo told me he paid $12 for the shells and the hardware was made at a welding shop in Barrio Chino (a Chinese neighborhood in Havana) for $10. In total the bongos were $22, but it was 1954.
Enclosed: Mongo's Vergara bongos, solid Caoba.
