I've seen the red and green but I was thinking that some may just be clear with different colored liquids inside top give them their color.
I wasn't implying otherwise, the bottles are all the same greenish glass (you can see the green glow at the base of the red bottle). You are correct that it is the liquids inside giving the color. the peachy orange seems to be less clear than the red and yellow for some reason.
These are my main reference images. The top one is a composite, as the red bottle makes a late appearance, and we never see the right side of that arrangement. Up until then changes are minimal.
By the way,
agent5 did you ever post your findings of what bottles you identified?
I can see:
Gordon's Gin
Jack Daniels
Jim Beam
Johnnie Walker Black
mystery Albi bottle
anything else? There are a couple small sort of ketchup bottle shaped ones I'm curious about.
They also used period labels for the other bottles behind the bar so I would think the label on these bottles would also be real, although not accurate on these particular bottles. Thoughts?
As I mentioned before, hexagonal labels seems to be super rare, so if it's real it's super obscure, but I'll continue to look. It almost looks like there is a black version and a white version, but the back lighting throws things off. They used so many that I was thinking it might be a fake label like Earl Hays Press makes, but, of course, Elstree wouldn't be using them. Who would they have been using for something like that?
My version was a good excuse to practice my label design skills, see the logo is a hexagon made from a camera aperture, since Slocombe was the director of photography.
