A navy person contacted me and said that this is not the correct set of gauges as they differed from what he dealt on his ship. I removed this item from the Sampson over 10 years ago so i have no memory of the conditions or where exactly i removed this. i was with a representative of Metro machine at the time.So that being said it's still a really nice set of actual gauges that were used on the Sampson. It contains all of the gauges, connectors and hoses for the ASROC launcher. A very unique piece of navy history for someone who worked on the ASROC launcher or someone who just likes the neat collection of gauges. One of the units appears to have been a substituent for an original and matching gauge with the rest of them. If interested i could find out about shipping but it's an extremely heavy case.
