Probably lettering in a popular style of the early 20th century, rather than a specific font. Note the tilde shape for the center stroke on E. Here is a somewhat similar digital font called Jonquin
http://www.myfonts.com/fonts/gatf/jonquin/
by a British foundry, Greater Albion Typefounders, which is "inspired by some hand lettering seen on a World -War One recruiting poster."
Move the tilde stroke to mid level and do some other relatively minor tinkering and you are in the ballpark for your lettering.
Other digital fonts with the E tilde include Tenebra by František Štorm
http://www.myfonts.com/fonts/storm/tenebra/
The E tilde is in the lowercase.

Can't name this one and doubting actually it could have been a font, more probably a sign painting or a custom lettering for Gieve(s) (which could make sense when talking about tailors to the King...).
I'm wondering also if the /E median crossbar is flame-shaped. Anyway, some clients for customization: Bolyar (removing some spurs), Trieste, Aviano Flare and Serif, LHF Cameo (my vote), Boston Truckstyle (interesting but enough elegant even reworked I guess), Esoteric 3

thanks for these, checkin them out…

You're welcome Matthew. There are some digital fonts with the flavor of the lettering of the era shown in your image. They lack the tilde feature and would need to be expanded in width.
1. Two independent digitizations of the another old font, name unknown:
Milton by Mecanorma [demibold]
http://www.myfonts.com/fonts/itfmecanorma/milton/
Musketeer by Tony Geddes [demibold, light & regular]
http://www.myfonts.com/fonts/mti/musketeer/
2. Kleukens Antiqua typeface designed by Friedrich Wilhelm Kleukens in 1910 for Bauer
http://typophile.com/node/52222
Sold under the name Trieste EF by Eisner & Flake. Veronika Elsner & Günther Flake did bold, medium & light weights
http://www.myfonts.com/fonts/ef/trieste/
Also Trieste SB by Scangraphic, bold, medium & light weights
http://www.myfonts.com/fonts/efscangraphic/trieste-sb/
Nick Curtis has a medium weight sold under the name Kleukens Antiqua NF.

3. Other fonts with some similarity and based on sources from the era include Windsor, P22 PanAm, and Edwardian.

As always, an amazing source of information on Typophile! Some lovely examples on here, especially Milton and Cameo, and the post here http://typophile.com/node/103815 is fascinating, learnt all about what a 'cyma' is!

Still no direct match, but we weren't really expecting that...

thanks

Matt
