Well-known

I just acquired this Regula R in beautiful condition and functional
(with RF a bit off on vertical and sticky slow speeds).
I have zero experience with Regula cameras but I found a web
site that claims:
http://www.mwclassic.com/articles/irregular_regulas/irregular_regulas.htm
"The rarest model of all was the Regula R, which was a meterless
first-type RM (or thus a fixed lens IIIc!). It shared the IIIc’s long-
base rangefinder and top plate, but the rest of the camera was
identical to the Cita III/RM."
Anyone ever adjust the RF on this series of Regulas? Any info
would be appreciated. Is the top as simple to pull as it looks?
