It's fairly easy to buy a "multimedia" European keyboard with 124 keys. It's somewhat harder, outwith Brazil, to get hold of a "multimidia" ABNT2 keyboard with 126 or more keys, but they are commercially available there, at least.
Here's one with 127 keys: https://mcinformatica.loja2.com.br/715631-Teclado-Multimidia...
Of course! I was never a fan of those flimsy hard plastic keys, so I didn't include them in the peak keyboard. This is more my taste: https://i.redd.it/hkb7kvqpob431.jpg
There is a guy making "new" model F keyboards out there, and if he ever makes an f122 clone I will probably buy it, regardless of price.
