Mamiya NC1000s Shutter Control Design Change
Thanks to reader Roland Stauber for the following
information. According to information obtained from a Mamiya
technician in Munich, Germany, the design of the NC1000s shutter
speed control was changed at some point during its years of production.
The change supposedly made for more precise and stable shutter speeds
over time. You can see this difference only when you open the bottom
plate of the camera. From the information currently available, serial
numbers lower than K150848 have the old design, and serial numbers
higher than K152262 have the new one. Where this demarcation actually
took place has not yet been verified. If you have a Mamiya NC1000s
with a serial number between these two, it would be appreciated
if you could
me with information to help verify this information.
If you happen to have any published data, copies of same would also
be greatly appreciated!

The picture above is from a Mamiya
NC1000s camera with the serial no. K105238. The red arrow points to
a linking arm (lever) which is in contact with the magnet (the magnet
is the yellow part partially covered by another large lever).
The bottom picture shows a newer Mamiya NC1000s (serial no. K228955). The
red arrow points to the same area, where a different (sturdier?) linking arm
is making the contact (both photos were taken with the shutter cocked).
