I think it's rather nifty. If it *is* designed to the original spec, it
probably took a lot of work. It also seems fairly sturdily made - two
pounds at 13"x5"x1". Look up Adam Savage's work trying to make a
perfect
replica of the Maltese Falcon from the film. It took him years to even get
close, and he's a professional model maker with connections in Hollywood.
