The MP-6 was made for the Japanese market only. It was basically the same as a regular MP, but it comes with the classic vulcanite leather found on the older Leica cameras, a Leica Camera AG Germany engraving on the top plate and on some of the later models an M6 iso selector. Although 400 were supposed to be made, only around 250 made it out onto the market. The camera is brand new in never opened sealed box!
