I found a fun & interesting site–
WW2 After WW2 All the leftover equipment, ships, planes & etc. (LINK)
Here is what they call a brick-a-brac section.
The cover photo and the color photo above were taken at Elizabeth City, NC on 17 February 1960. It shows the last PB-1G (USCG nomenclature for the B-17 Flying Fortress) still in US Coast Guard service; also the very last Flying Fortress of any version left in any of the five armed forces; alongside the USCG’s first SC-130B Hercules.
THIS LINK tells how US Minesweepers were used as Soviet Era Whaling ships.
As well as how many are still being scrapped today.
Lots of other interesting stuff, about the largest military production effort in History.
And the many things that are…leftover.
