I was the technical representative for Fairey Hydraulics Limited working with Cadillac Gage on the Lav-105. The auto-loader developed for the lav-105 could load and fire 8 rounds of 105mm in one minute while in motion. The picture of the lav-105 was the first shot and all the test cords for instrumentation can be seen coming from the turret. The pictured shot was at the ARES firing range between Toledo and Cleveland along lake Erie. 105mm TK shell casings sell for $350 in most collections. I'm only asking $250
