I'm finding no solution or thread to this problem anywhere on the net.. Can any one help or has the answer or tried cleaning this lens front or front elements ? Just picked up this old Polaroid 180 land camera from an old shop. Its in great working condition..but lens has lot of fungus within its first two front elements.I've tried everything from removing bellows and taking off back element. but seems no answer to taking off the front. Just want to know how you take off the front element Please help..
