I know nothing about Brownie cameras but have been searching the net for info regarding a No. 3 Brownie. So far I have found nothing. Is it considered the same or equal to the No. 2? Do you know the value? The one I have seems to be in very good condition - probably would work if I knew how to clean it properly, find film, and figure out how to operate it. I'd appreciate any info! <p> Thanks!
