Q: 4. What accessories would we need to enlarge 6x6 film to 50x50" paper hanging on the wall?... lenses, filters, film holders, etc. But also to 20x16" on the table.

A: The Beseler 67XL-VC-W would already have built in variable contrast filters to use with variable contrast papers. A suitable negative carrier would be the Beseler 6x6cm Glasssless Negative Carrier, BH # BENC6667. As for the lens, you would also need a lens board and a retaining ring. A lens such as the Rodenstock 75mm f/4.5 Rogonar-S Enlarging Lens, BH # RO7545RS combined with the Beseler Lensboard for Printmaker 35/67 Enlargers, BH # BELB39PM67 and the Beseler 39mm Threaded Lock Ring, BH # BEJN would be great to use.
