I had a bit of kit values at £130k. ASAIK no one signed for it except that every year some Army wallah would send us sheets and sheets of inventory audit paper work with the item listed.
More precisely, a similar item was listed with a similar NSN but a quite different serial number.
We would correct the paperwork and return it.
Next year another set of paper with similar item listed with a similar NSN but a quite different serial number.
As we didn't keep the paperwork I have no idea if it was the same wrong info from the year before or another set of fictious numbers.
