It is true that there aren't a lot of choices on the local Polish market for large format cameras. In the shops in Kraków I've seen a few Linhofs, some big Soviet studio cameras, and not much in between, and the pathways for purchasing a camera through the Internet are different due to language and perhaps methods of payment.

Argentum in Hungary seems to be surviving, making affordable wooden LF cameras.

A business making LF cameras in Poland could also be a business selling lenses, filmholders, film, and other accessories.
