I repeat here two complete and large answers that I
wrote to the old RUG about the Rolleiflex MX-EVS
models or Rolleiflex 3.5B according the factory
original name (and the author Claus Prochnow):

I can answer you following Prochnow. The MX-EVS is the
3.5B for this author, he does not distinguish Type 1
or Type 2 but there are some differences within this
model, enough for other authors to distinguish 1 and
2. This was the first Rolleiflex TLR with EVS system,
it was manufactured between April 1954 till September
1956, there were two serial numbers blocks for this
camera:1,428,000 till 1,499,999 and 1,700,000 till
1,737,999.- 94,000 3.5B or MX-EVS were manufactured.
The camera was provided with three different taking
lens:Tessar 3.5/75 (Carl Zeiss Jena), Opton Tessar
3.5/75 (Carl Zeiss Oberkochen), Xenar 3.5/75
(Schneider). This camera used the linear Synchro
Compur CR00 MX for the EVS for the first time in a
Rolleiflex. From the camera serial number 1,700,000
(starting the second serial numbers block)were
introduced improvements for the EVS, i.e. the neutral
or free position and other that I'll look for the
meaning afterwards. For the author Evans these
improvements are enough to call the 3.5B "MX-EVS Type
2" from the serial number 1,700,000.- 
Sometimes I receive some questions from two or three
of the 370 Rugers (RUG+Digest) that don't write to the
list in general but read the messages about Rollei
cameras and lenses, I answer one of the question here:
As I wrote in my previous two messages (see
below)there were three technical moments for the EVS
development. The first moment we can find in the
firsts 3.5B or MX-EVS Type 1 cameras, these cameras
have not the middle button in the diaphragm wheel to
lock-unlock the system, these cameras are from the
serial number 1,428,000 till 1,464,000 (this block
complete is till 1,499,999). These rare firsts MX-EVS
have engraved the word "Germany" in the diaphragm
wheel, Prochnow shows a photograph in 16-358. I think
this camera is rare today because the serial numbers
block is shared with the 2.8C.- From the serial
numbers 1,464,000 till 1,499,999 was added the central
button that you need to maintain pressed to unlock the
EVS, I think this camera is well known and in general
the users indentify it as "MX-EVS type 1", but really
it is a second evolution. Prochnow shows a front panel
photograph also in 16-358.- The 3.5B "MX-EVS" Type 2
(according Evans name) has the EVS mechanism more
perfectioned with the position free wheel or neutral
wheel avoiding to maintain pressed the button to
unlock the EVS, this system is also used in the 2.8D,
3,5E and other Rolleiflexes, this is a third
evolution, Prochnow shows a front panel also in
16-358. This evolution started in the second serial
numbers block for the 3.5B, 1,700,000 till 1,737,999.-

All the best
Carlos
