Leica M3 DS (1956) Rangefinder camera

Stunning example of a 1956 Leica M3 Double Stroke.
It's an early-production version, so it has features different from later M3s:
1 - The strap lugs are called Budda Ears because of their shape
2 - The shutter speeds are those preceding the international scale 1/5 1/10 1/25 1/50 1/100
3 - The ASA indicator goes up to 200
4 - The film pressure plate is glass.
5 - The back door has two small pins that secure the snap closure.

These features are not present in later models.
The camera has been serviced about 1 month ago before being offered for sale.
Everything works properly.
