【Excellent Condition】Leica Viewfinder 50mm SBOOI with Leather Case

Thank you for looking.
This is an Ernst Leitz Leica viewfinder 5cm 50mm SBOOI.
This is a 1:1 magnification viewfinder for Leica.
I acquired it from a collector in the UK.
I previously owned several, and the optical clarity of this one is exceptionally beautiful.
It's a gem that makes you happy to see something over 50 years old has been so well cared for.
It comes with its original Leitz-engraved leather case.
I like the look of it on an M3, but I've only taken it out for actual shooting a few times.
Please understand that the M3 and other items shown in the photos are not included.
I've uploaded photos because of its beautiful appearance.
There are minor scratches on the exterior, but considering it was manufactured in the 1950s, it is in very good condition for its age. The glass is clear and free of fogging.
I am selling off my collection due to my age.
Although it holds many memories, I am listing it because I want to pass it on to someone who will use it next.
Thank you for looking.
