I own a B&S Bariton or baryton 2046 which is of course oval. A lot of fun to play and gets a lot of attention here in America. I normally use it in community bands which drives players crazy with the bell direction. I have used it as a solo instrument and been told sounds much like a French horn. Not much of a market for this horn in America and I overpaid for it, but I love it.
