Want to Buy WTB: Bronica 50 f3.5 PS

I recently bought a SQ-AI and I think I'm in love with this system. Since I already own the 80 mm PS and 110 mm PS I'm looking for something wider, like a 50 mm PS. I might settle for a non-PS lens as well, I'm not that picky

I live in Sweden (northern Europe) but I can pay for international shipping if it matters.
