Hay Joe,
Noticed your L&HRRR whistle post on the forum and it reminds me of when I had gotten mine in the Allamuchy area of N.J. in the woods. That sucker had to weigh around 300 lbs. Concrete with rebar support. I broke my a__ __ taking that thing out of the woods. Went back at a later date and got about 1/2 dozen wet cells still in the ground vault. Used rubber gloves just in case there was still a strong concentrate of hydrochloric acid in the rain filled vault. At a later date I found a single head target, complete, except for spectrum (gone). The funny part of the whole thing to others, of the story, is that when I opened the back of the target cover to see if the spectrum was inside, out jumped a squirrel and I almost had a heart attack and came close to falling off of the signalman's platform. DON'T LAUGH!!! Loved doing this once in awhile! We'll have to get together to check some other areas out sometime!
