Sl66 6x4,5 horizontal 4,5x6 vertical Magazin

[filadentron]

Hello for everybody!
I just joined to the forum, because i plan to buy a rolleiflex sl66. I was very happy seeing this page, providing a lots of information for me already. So thanks a lot. I am looking for the horizontal and vertical variation 6 x 4,5
magazin for the rolleiflex sl66. I did not find any on ebay. I searched over the whole internet, with no results. Are these magazins realy so rare or Im just too stupid and searching it at the wrong place?

Thanks a lot for your help
