Could be a genuine horn sinew composite (but I'd guess not). there are a lot of f/glass (spits on floor) horsebows being imported from China.
(I'm not China bashing, as that style of bow is part of their heritage).
A few guys at the club have 'em, make a change from longbow. They are cheap and good fun, they are generally leather covered so they look authentic.
I have one I made myself from old f/glass lams from my old crossbow making days.
