The Britool 7/16 drive socket set with which my father earned his living, and with which I earned my first money in Engineering, now resides in The Old Workshop in The WaterWorks Museum in Hereford.
All but one of the sockets are original (WHAT doe that say about the quality? )
Someone will find a use for them, especially the larger sizes.
Oddly, I don't see modifying a tool for a specific purpose, as long as there are duplicates in original form, to be vandalism, but as producing a tool for the task. My preferred material for such modifications tends to be lowest value example of the tool that is available.
Very often, "The Devil drives, where needs must"
Didn't really like doing it, but 140 miles from home and the correct material a M6 nut was modified with a 1/4 BSW Tap. to meet an immediate need.
ie Would be more likely to convert a Ford Escort into a hill climb special than Bentley! (Perhaps that's why so many "chain gang" Fraser Nash cars suffered that fate )
