Trade for 112mm B+W or Heliopan Circular Polarizer.
What else would I consider as a trade ? For starters, I could use a Phocron shutter tester or always wanted to try a Fujinon lens in Copal 0 on my 4x5. Also, it would be nice to have a backup exposure meter maybe with flash. 112mm filters: quality brass ring ones eg Polarizer, yellow, orange, red filter. Epson 4900-series or i900 photo scanner. Trade TOWARDS a Epson V700, 750, 800 Photo version Scanner.
