I did get an original case, which differs BTW from the earlier models (Automat) and latere ones (2.8E and F) because it has a different strap. I did not like the original strap, but the case is nice. My strap was renewed, never trust original ones. Still, even with another strap which fitted the connection, I decided it was not safe. I have the strap attached to the lugs, not the pin.
However, since I always use the hood, I just put it in a bag without the case: either the ThinkTank retrospective 20 or Billingham 307, both with other cameras besides. It is much more practical, esp. since you need a handheld light meter unless you work with the Sunny-16 rule.
