If I'm not mistaken, I have a set of 8 pterosaurs marked with SH as well. It appears to be a Chinese company of low-end figures, but it's otherwise hard to say which one.
Looking for animal figures? I have an actual online store, out of Canada! [You must be registered and logged in to see this link.][You must be registered and logged in to see this link.]
I'm also a big freshwater fish-figure fan. Know of anything new and exciting? I need to know as well!
