Thumb rest for Leica M10. I purchased this new from Map Camera. The material has a similar texture to the M10, providing a seamless fit (and a substantial weight). I am selling this because I have sold all of my M10 series cameras. It has been cleaned. There are no major scratches such as paint peeling, but there is some wear and tear from normal use, such as scuffs on the part that inserts into the hot shoe. For reference, I tried attaching it to an M11, and it was possible to mount it. However, the texture is slightly different, so those considering using it with an M11 series camera should be aware of this (including the fact that it is not officially a compatible model).
