Just noticed the inside of my Polaroid 250 Land camera has a saggy bellows on one side. I guess that's what was causing all of those undeveloped streaks on the recent pack of 3000b that I just shot with it. I pushed the cloth back into place into place so it shouldn't be obstructing the film but the entire bellows should be replaced. Everyone says to just swap out the bellows with one on another Land cam when this happens. I do own a 100 & 420 but those have grey bellows and I'd like to keep my 250 looking 'stock' with a black one. Is there any place online where I can buy a new one from? Or is my only hope buying another Land cam with a black bellows and swapping with that?
