Help to ID a set of handmade congas

Hi Everybody,
I know the amount of wisdom in here is enormous, so I thought you could help me out on this one. It's a set of 3 drums I'm thinking of buying. The only thing seller knows is that they are handmade and have cowskin on them... Any additional information would be highly appreciated (wood, maker, year, etc.). Below are the pictures I have:




Thank you
Magnus
