It is a 6x6, not a typo. As mentioned, SQ=SQuare negative.
Thanks guys! Glad to be part of this forum.
Bronica SQ in excellent condition. Bronica 50mm and 80mm lenses with caps, two film backs, dark slide, waist level view finder, custom Pelican hard side waterproof case, instruction manual. Since going digital, I very rarely use it, but it makes fantastic images! I will consider any REASONABLE offer.
