All good stuff, Mac. I have everything in a spreadsheet with new value, replacement value, serial number, photo and the location of a unique identifying mark, a different type of mark on each instrument and in a different location. That spreadsheet is stored online, on a thumbdrive that is always with me, on a CD, and each computer, and a copy of the disc is in a bank safe deposit box as well as one in my fireproof safe with my will, etc....
Of course if they take the stuff an head for Guatemala....
But I have taken every precaution I can think of.
