Rolleiflex SLX and 6000 series External Battery adapter (Used but Excellent)
This adapter has a battery receptacle and plug that allows you to mount the battery further away from the camera - to save weight, or to keep the battery in a warmer location such as a pocket, etc. Will work also with the Rollei Lens Control S
It's not a battery just an extension cable - and a battery is not included. But If you were enterprising - you could of course adapt this to work with any other battery source such as a quantum turbo or other suitable battery pack for extended duration supply.
Condition is excellent, lightly used with almost no marks. This is only the 2nd one that I've had come through my shop - I don't see them often!
