Offered here is a vintage Army DT60 Dosimeter Calibration set.
This set was last calibrated in 1966....It has been in storage ever since. This was from the Canadian Army - the same kit was used in the US Army as far as I know. All items are made in the USA. The kit includes the 5 x DT60 dosimeters shown in the picture, the case, foam inserts, and calibration paperwork that matches the serial numbers on the dosimeters. This is a rare addition to any Vietnam Era NBC display. These are seldom seen army surplus items. What you see in the pictures is what you get (nothing more / nothing less).
The case has no cracks or holes, but will have markings, stickers, writing, tape, and wear and tear as seen in the pictures. These were last opened in as far as I know at the time of calibration - I recently opened them for the eBay pictures and to verify the contents. Everything looks and works just like it should.
