I made my first Blade Runner pistol when I was 18, while living in Hell's Kitchen, NYC. I stared at the VHS version on pause and made sketches. Put it together from toys and model kit parts. It's lovely and terrible:
(Years later the internet would teach me that the six dollar plastic gun I bought on Canal street in NYC and cannibalized for the grip was created by Edison Giacattoli, a legendary toy gun designer)
I made a crazy accurate scratch-built when I was 30, from resin and bondo. I had great picture reference but shitty size reference, it was 20% too small. Fuck!
