This was in excellent condition a big chunk of camera with a very nice lens only issue was the very faint image using the rangefinder although all the mechanical gubbins work including the parallax correction and the case was in poor condition but did its job protecting the camera.
There was no need to change any light seals as this camera doesn’t need them all the seals are mechanical (very nice engineering 🙂 ).
Like most cameras of this time it used a mercury cell as the voltage was steady throughout its life at 1.35 volts fortunately a zinc air A 675 hearing aid battery is a good working replacement with a very similar voltage and a flat voltage output but may require a little help as its size is not the same as the original an alkaline battery such as the EPX625G could be used as it is size for size to the original mercury cell but will give slightly variable reading dependent on the voltage through its life.
The Hi-Matic 7 is no lightweight but still nice to handle.
