I'm not finding that, mind you I don't have a recent accordion.
But my 1959 Hohner Lucia has worked without any faults since I did an extensive restore 3 years back.
I would say the basic materials for a decent accordion haven't changed in 60 years. although these days you do get plastic reed blocks apparently.
If it was put together properly 60 years back it should still work fine, the only bits that will fail are 'consumables' like pallet facings, leather valves, and felt inserts - but those should all be replaced periodically anyway.
Doh, forgot bellows, they will wear out eventually.
