I have recently bought a number Rolleimarin spares.
Amongst the parts was a packet of speed control knobs marked 3.5 E3. I know
about the ones inscribed 3.5F, that is no problem because that is the
Rolleimarin 4. I have not come across any mention of an 3.5E3 version. Does
this mean that there was a Rolleimarin 4 and a Rolleimarin 4a of 5??
The Rolleimarin 1 is for the 3.5A, the Rolleimarin 2 for the 3.5B (which in
essence is the same as the) Rolleimarin 3 for the 3.5C and the Rolleimarin 4
for the 3.5F. The knobs I have marked 3.5E3 are very different to the other
knobs for the four Rolleimarins...
I thought that the E3 was a hybrid 3.5F and 3.5E2.
I am trying to ascertain why this model would have a different speed control
knob, but there may be other differences too...
I was also wondering if the focus graduations are the same as either the
3.5F of the 3.5E2 because the RM4 focus knob has a different part number. I
also don't know whether the aperture dial is the same as the 3.5F or not.
Does any one have an E3 and an E2 as well to compare their three dials; also
against a 3.5F would be useful. I think the important part is the distance
of the graduated scales between the first and last markings, ie between B
and 1/500; infinity and 1 metre and f3.5 and f22. A major difference between
the 3.5E and the 3.5F is the wider lens spacing. The 3.5E3 has the same
spacing as a 3.5F but maybe there are other 'undisclosed' differences
too????
Thanks for any observations that will undoubtedly be made!
