Well Richard , they likely were much better … until they cracked open… do we know ?

So when and why did many/most eventually crack open ?? did pressure from chemical decomposition build up and split them open? or did the case dry-out and shrink? Or did ?storage temp swings and humidity do it? , etc?

Possibly ageing tests were only for 10 years ?? was there a standard by RMA or ? that? addressed life [expectancy]?

Are there radios that survived without cracking ?cap casings because they entered a good care-home at an early age?

Not done with babbling thoughts, but fingers were not rated for so many years either, so I give up.
