Thanks all.
@John my cambro is type 53883 (or at least that is the number I found on it) I haven't got a tripod yet for it. Trying to get one 2nd hand. But I have to save first.

@HKA Wich part exactly? I am originally from Twente. I am a tukker so to say.

@Geert This one was on sale from bankrupt PDA photography in Hilvarenbeek. I stumbled upon it and thought it would be a great opportunity (cost me only 181 euro's) I'll see if I can upload some pick in the correct forum here.

So the start for 8x10 polaroid has begun. I discovered yesterday I also have a back for I think 5x7. Pretty cool to have so much choice in format.
