I personally think that the very first version (type1) with its interlock annoying to use and the Planar lens of the type 1 often has a separation, another point is that it´s a pretty cool looking camera if mint (and very hard to find in mint condition too) and it has definitely a different character compared to the type 3 but what is type 2?
Some time ago I got the Rolleiflex what I thought should be the type 3 in absolutely mint condition but it turned out that it´s the type 2 and it actually the first type 2 I had in maybe 10 years!
My first expression was just, "wow it works UNCOUPLED!" yes, unlike the type 1 the type 2 works uncoupled what is a big improvement over the first version and it also makes the coolest satisfying sound if you change the time setting!.
BUT IT ONLY STARTED WORKING SMOOTH AFTER A FULL REBUILD AND RE-LUBRICATING THE WHOLE COMPONENTS OF THE PLANETARY Synchro-Compur SHUTTER
it definitely should not turns stiffer because of the extra gears...
So the process and the result.
