Steve, I have a long experience using Bay II lens
hoods, first with my former 3.5E and now with the
3.5F, the Bay II lens hood has a point where it fits
easily, it's very difficult to fit if you can't find
the point, the point is between 10 and 11 hours
considering the F&H logo position regarding the 12
hours position on the taking lens outer ring, if the
lens hood is in the right point you turn it to 12
hours and it clicks easily at 12 hours coinciding the
12 hours position for the lens hood and taking lens
ring.

many thanks for the info. since my camera was lefted in my home and i am now in office, i will try the operation you mention as soon as i go back home.

but, by far, after checked the picture you proviced, i believe my lens
hood don't has the cut shown in the picture. it look like  what you
mentioned the ebay item 170016871225.  and i can remember, the lens
hood has a 'Rollei F&H' logo and an engraved "34Î' mark.  however, it
has three inner cut in its inner ring they spaced with each other in
same degree.

can you say more according these clues?

BTW, the lens hood Bay II for 3.5E and 3.5F has a
special cut on its ring with an also special shape
allowing to fit it in the taking lens outer ring and
avoinding the contact with the viewing lens outer ring
(and with the shutter speeds wheel), the lens hood
covers the taking lens outer ring thanks to this
special cut.
If your lens hood has an entire ring without cut it
could be a Bay I lens hood for Rolleiflex 6x6 and
Rolleicord, or it could be a lens hood for 2.8A,
similar Bay II size but with an entire ring like the
Bay I lens hood I have mentioned, I think this lens
hood would be very difficult if not impossible to fit
on a 3.5E or 3.5F, I never tried it.
Prochnow in the Rollei Report II, pages 24-510 and
24-511 shows the photographs about the lens hoodss
manufactured for the TLR from 1947 and their
descriptions, he distinguishes between lens hood with
"axialer Klemmung" and lens hoods with "radialen
Raststiften" according the way used to fit them in the
taking lens outer ring ( I know the practical meaning
for both fitting ways but I don't know the exact
translation from German into English, the first one
would be something like " axial wedging" and the
second one something about "radial pins").
The 3.5E and 3.5F lens hood have "radialen
Raststiften", and the lens hoods Bay 1 for 6x6 and the
Bay II for 2.8A have "axialer Klemmung", both types of
lens hoods rings cover the taking lens outer ring, but
they work different. The 2.8A lens hood has the F&H
logo and "34Ã" according you can see in the photograph
clearly.
You can see a Bay II lens hood for 3.5E and 3.5F
cameras here:
http://www.collectcamera.com/pagesrollei/hoodscaps/hoodmetalbay2b.htm

and you can see a Bay I lens hood looking for the item
170016871225 on eBay, the 2.8A lens hood looks very
similar.-

All the best
