I have seen one with a "Made in Poland" label, having been curious about these myself and keeping an eye open when out and about.
Even Krosno itself isn't a single maker as such, but was an area where there were several very good makers were in operation.
(I got in a terrible tangle several years ago, wanting to visit the maker "Krosno".

)
It eventually got taken over by the distributor LSA and their labels are found now, rather than ones saying Krosno.
