Actually I misspoke about the size, it takes 2-1/4 by 3-1/4 plates (6x9), there was also a bigger Maximar that took the bigger plates. I have looked on ebay but the same type of holders (that also work in the same sized Recomar) are selling for like 3 for $45 - seemed a bit steep to me but maybe not. I will have to brush up my German and try the German site, thanks for the tip.
