It looks very similar to the vintage coat that kitonbrioni has posted pics of (the one on the far right, sorry for stealing your pic kb):
The Eldridge I have is quarter lined as well; the pockets are very similar as are the turned back sleeve cuffs.
There's only one button hole on the lapel on my Eldridge, but it actually is functional as there's a button high on the right side that it can be attached to. It also has a lapel buttonhole flower catch on the underside of the lapel beneath the buttonhole, a feature I've only seen elsewhere on Oxxford.
