Not so much a twit as the reproduction organ of your choice
The aircraft parts were given to me by an opposite number at a company I did work for years ago. Once, after a meeting we got talking vintage aircraft. He was involved in wartime archeology and I mentioned some of our own procedeures could clean up and/or halt corrosion so in helping him I got some very nice bits and bobs along with other infor and stuff.
I kept them all at work and had taken the older of my Fathers tools for some treatment.
As with most things like this you think you can get onto it at anytime and with that years passed, I got ill and eventually left and then that division of the company was sold. I remained a keyholder and the CEO is a good friend of mine so I was often in there when one day I certainly thought about the stuff.
It is most likely all the stuff was skipped through ignorance of importance - certainly as far as the aircraft stuff was concerned.
Someone may have kept the tools - I hope so.
It was a period of years where my health, my wifes health and my eldest sons all took a turn for the worst along with a ton of other crap we could have done without. However, we are still all here
