I bought these bongos from a boot sale for £1.00GBP. The guy wanted a tenner and i told him the bongos are worthless especially with a broken skin. He knew no different so he said give us a quid as a gesture. These bongos are rare these days Made in England and named after the famous Edmundo Ros. These were made by John Grey 50'S/60'S. I wrap all my own drum heads with calf skin so wrapping these no probs. Ive been making my own drum heads for the past 20 yrs. What i do need if anyone has one is the John Grey tuning key for these.
