I think my camera dated to around 1948, I looked up the date but
don't remember it. The shutter button is the old thin kind. The shield
that rotates up seems to be there to prevent accidental exposures. This
one has the cable release socket on the lower right front (facing the
camera). It does not have flash synch.
My later MX, about 1954, has the shutter button that is threaded to
take a Compur type release but is also threaded on the outside to take a
Leica cable release. This has a shield that will catch the threads and
hold the shutter open. It also serves to hold the shutter button from
moving when the cable release is used.

Yes Richard, the Rolleiflex 3,5A or 3.5MX from 1951 had this feature, it seems it was the first Rolleiflex Automat to have it.

The lock also made time exposures possible on cameras with only a
B setting. Not all cameras with a protective cover on the shutter
tripper will lock it in B, for instance my just post war Rollei
Automat. That needs a locking cable release.

I forgot to mention an additional function for several Rolleiflex
TLR models and SL66 shutter release locker rings: Pressing the
shutter release button at B and turning the locker ring, the
shutter will be open up to you turn the locker again, this way
you can keep the shutter open for ever. Jan could use this
function if the tripod was good.
