Russian Bukashka-3

I have two Bukashka-3s. I aquired the first one from John Weinel in 1990 and the second one from Robert Allen Steed in 2006.

The Bukashka-3 appears to be made of two pieces of aluminum (or titanium?) welded together. The functional aspects of the Bukashka-3 are similar to the Forrest Triton. The tab at the top appears to be nothing more than a cool place to grip an overheated device. The lower carabiner hole is too small for some of my carabiners.
