What were the names of Antonio Stradivari's sons who worked with him?

His violins are the world's most expensive.

Player #14782264, that is why they put the option in there, to make you think!

what weird name the second son has got, Omobono, still it's not going all funny on the spell check, so it might mean that it's ok?! wouldn't like to try it on a email tho, somehow?

Player # Blue Moon., 😂
