Interesting design, never seen or played one like that. Anyone have any knowledge or experience with this?

Here's a current Lidl BBb at Horn Guys.



Here's the one on eBay:



Other than the shape of the valve paddles, S-links and clock springs, they look very similar. I'm guessing that the one on eBay
is quite a bit older than the new one at Horn Guys.

Somewhere here, there have been comments and a review. The reviewer liked it and it is a good example of a small, relatively light BBb tuba.
