They are very common here in southern Ontario in 12 gauge but much harder to find in 16. I used two 12 gauge ZP-49's to build a double rifle in calibre .450 #2 Nitro Express with a second set of barrels in the original 12 bore, fitted to the same frame. This rifle has fired between one and two thousand .450 #2's and is still tight and on the face. I am currently building another double rifle, in calibre 9.3x74R on a BRNO 16 bore ZP-47. The materials used in these BRNO guns is of top quality and they are well-hardened, so much so that I've had to use diamond-coated files on the guns to remove pits and to re-contour some areas. Also, as info, these guns were made in several different grades, with the highest grades being extremely nice. I see them selling, in the standard grades, for between $300 and $550.
