Thanks, that's right the information I needed :up:

No remarks? :D

Hard to say. Plain black is very unlikely. Maybe plain red. I don't think it was an isolated danger mark, else, they would have just added a simple buoy, and not built a whole concrete tower. :hmmm:

Edit : But a red tower with a green light ? (from 1911)

I agree

Maybe :hmmm:
Look at the picture below portraying the nearby Tourelle du Chat:



You can see a coat of what looks like a solid red paint under the current black/yellow paintwork. Other lighthouses or day beacons with solid red or mostly red paint (possibly used as lateral marks):

You are right, it makes little sense, unless the steady green light was replaced with something else on a later date...

That's not so uncommon in especially dangerous areas, where the beacon and the light on top of it (if any) are better spotted from a longer distance than it is possible with an 'isolated danger' buoy:

All you need to find is the local "plan" for the lighthouses circa 1938 or so... easy peasy :roll:

The US University of North Carolina apparently has someone interested in lighthouses around the world:
https://www.unc.edu/~rowlett/lighthouse/
perhaps someone there could direct you to historical data?

.... and here also : http://www.haka-spirit.net/spip.php?article159

Especially this sentence :

Which means you can pass on the right or on the left of this red tower.

OK. I agree to choose plain red mask, with a west buoy light, or simply red fix light.

:lol:

We know that website all too well: it is our main source of information :up:

I have never thought of getting in touch with the guys at UNC. That's not a bad idea, though I suppose that the information we need is more easily found in some dusty French archive lol :)

Probably in 4S ...

What if, after all, the Tourelle de la Plate was painted dark green and the nearby Tourelle du Chat red? They might have marked the narrow navigable canal between the Chaussée de Sein and the Pointe du Raz (i.e. the Raz de Sein itself) as a couple of lateral marks rather than as cardinal marks. Does it make sense? :hmm2:

Are those files accessible to the public? :D

Yes. :yep:

I think they are.

Probably the most logical configuration, and in accordance with the steady green light recorded for La Plate in 1911.
My one doubt is about the unusually dark shade of grey representing the lighthouse in the historical picture you have pointed me to. Human eye's spectral gamma and the one of B/W films are quite different. Usually, red shades look much darker on old B/W photographs than they would have looked to the nake eye, and conversely green shades are recorded as ligh grey, much lighter than the eye perceives them. This is especially true for old films and orthocromatic emulsions.
Going by the tone of grey seen on your picture, we should conclude that the lighthouse was painted red rather than green; nonetheless the picture might have been taken with a panchromatic film which is proportionally lesser sensitive to green than to red, and/or the green paint used on La Plate might have been unusually dark. The tower beeing photographed on the background of the brighter ocean surface, might also have enhanced the darkness of the tower, making it to appear as a silhouette...

How? Were they digitized? :hmmm:

If you look very close to the photography, you can see something looking as a darker band on the tower :

perhaps a red band on a green tower, or a black band on a red tower ? :hmm2:

mmm... possible, but it is difficult to guess the exact paint scheme from those few pixels.
We definitely need a better picture, or a textual confirmation of our guesses.
Conversely, what seems already clear to me is that the gas tank/lantern platform had to look more similar to the drawings below than to the one seen in recent pictures :yep:

First post updated with new lighthouses, and no more searchlights but naval bases, so you can see the names on your navigation map.

Type 408 not defined for LHLaPlate!

What are you testing Anvar?

Here with all the latest mod/patches, everything works fine :hmmm:

Yesterday I have found this useful website, with accurate positions of many French lighthouses, navigation beacons and landmarks that we weren't even aware of:
