Thank you for these informations.
I measured mine however, and the diameters are 10,5"" and 10 3/4". Maybe because they are "mini congas".
I saw the red model once on a second hand website, but it was not in such a good condition as the one I recently purchased, and the seller lived overseas, which meant expensive shipping costs and damage-risk.
Are you sure mine are "real" mahogany, rather than Philippine mahogany ?
The only mahogany I've seen "in real life" is red (I mean Caribean mahogany, the only one I know).
I don't understand why other conga manufacturers never attempted to copy or license the design.
Except for LP or Meinl "conguitas", a former famous french drum maker, Bernard Mauffret (the brand Baak, if some of you guys know it) built once a set of those mini congas for a french drummer who toured at the time with Johnny Clegg. I can't remember how they sounded, nor what the drummer meant about them (I met him once and chatted a while with him, but it's a long time ago), but "normal" Baak congas were top-of-the-line, as good as Delaporte. Bernard Mauffret has now given up drummaking and makes only furniture. Too bad...
