I would be grateful if anyone could help me find fonts that are similar to this lettering on the Queen Mary's Art Deco Observation Bar. Primarily looking for the main "Observation Bar" lettering but wouldn't mind knowing the secondary "An Art Deco Lounge" part as well. Thank you in advance for your help!

So far I have not found a single font has this particular combination of wide and narrow letters.
Yasashii Hairline Bold has similar _O_, _B_, _S_ and the top loop of _R_.

Bougainville Book has similar _E_, _R_, _V_, and _A_

Breamcatcher has similar __N_, _V_, and _A_

Donshottype,

Thank you very much for the suggestions. I don't feel bad now that I could not locate a font for this. Looks like custom lettering not based on any particular font or style of writing. Bougainville is very nice. The "O's" are more narrow but the rest of the letters look pretty good. Thanks again.
