Bach / Brandenburg Consdertos / Leonhardt (1976 recording)

On 12 July 1996, I wrote:

Almost three decades later, I obtained this -- for myself:
Brandenburg Concertos (1-6) by Gustav Leonhardt (conductor) with Frans Brüggen, Paul Dombrecht, Sigiswald Kuijken, Wieland Kuijken and Claude Rippers, recorded 1976, RCA Red Seal, 2 CD set, RD 70794(2).
The set is in mint condition, including the original price tag of the V&D department store: 32.00 Dutch guilders.
I paid only €16 including friendly service (detailed replies to my questions) packaging & postage.
More later!
