Thanks, Tom, I wonder how much the government had to pay for our Brunton gear, LOL ! The one that I used was one heck of a nice instrument and was "militarized" well including shock mounting (and protective covers for transport).
A performance update for the protractor: last night I disassembled the protractor (at least to the degree possible), thoroughly cleaned and lightly lubricated it with sewing machine oil. After wiping down and reassembling, I find no error greater than one minute when measuring my entire set of angle blocks. VERY impressive tool !
