With this adapter you can use a Bronica SQAi 6x6 or ETRSi with TTL automation in combination with a Metz 45 CT-4 or 45 CL-4 for flash photography. The adapter is in a good condition and comes also with a standard flash connector cord. I sell this adapter for 100 Euro or US$130. I sell it because it came with a recently acquired Bronica SQAi kit and I already had one for my 4.5x6. If interested, I can sell it in combination with a Metz 45 CT-4 flash gun in good working but of course used condition for an extra 75 Euro (97,50 US$). A camera bracket and a charger are included with the flash but the nicads won't charge any more. However an adapter for 6 penlights is also included so you can use standard AA-batteries. Additional adapters for AA's are easily found on Ebay if you need them. Contact me for shipping costs.
