How to Remove the Top Cover of a Leica M3

The Leica M3 is a classic rangefinder camera that has been sought after by photographers for decades. It is known for its simple design, its accurate rangefinder, and its excellent image quality. However, the M3 is also a delicate camera, and it is important to handle it with care. If you are planning to work on your M3, it is important to take the necessary precautions to avoid damaging it.

One of the most common repairs that Leica M3 owners need to perform is the removal of the top cover. The top cover is the metal plate that covers the rangefinder and the viewfinder. It is held in place by several screws, and it can be removed relatively easily. However, it is important to be careful when removing the top cover, as it can be easily damaged.
