It's a bit ironic that things we did not value too much back in the days like brake lever hoods are turning out to be the hardest things to find when restoring a C&V bike.It's just their very perishable nature and the fact that many brakeset makers from back then are long gone, means we eventually hit dead ends in our search for these parts......
Heck, even brake hoods made by the biggest companies that are still around are becoming unobtanium, like Shimano's 7400 series brake lever hoods. Shimano made lots and lots of those brakesets and you can find them easy enough......but it would be a different story for the lever hoods.
