In addition, such previous model already considered as "Legacy products" on Trezor website. Usually there's no good reason to buy those over Safe 3, 5 or 7.
You wouldn't be able to buy them from the official website even if you wanted to. They no longer sell them there. I am pretty sure they are still being sold by resellers, though.
To initialize my Tangem cards I used one of the child SEEDs generated on my Passport Core from its master SEED according to BIP‑85 standard that Passport Core supports.
I didn't even know how many hardware wallet manufacturers support BIP-85 until recently. The list is decent. Brands like Coldcard, Jade, Bitbox, Seedsigner, Krux, and probably others support child seeds. Trezor unfortunately doesn't.
