Interesting. I have a similarly styled one, with no branding, LOL, but adjustable height. It's pretty nice, as far as height adjustability, but kinda heavy. I just recently found another black Cinelli stem, with a bit more reach than my old one, but it had a badly cracked wedge. So now I have 2 stems & one wedge. (?) But the newer one definitely has the alloy bolts, nice & light.
