"Traditional" regulation doublet?

[JWLC]

Hi all,

Some months ago I picked this vintage doublet on eBay . I've seen on the forum photos of jackets resembling this one, which leads me to wonder whether this might have been some sort of early regulation doublet after all, as opposed to the Prince Charlie facsimile as we know it.

It differs from the 'modern' regulation doublet in that the tashes run across the entire front hem. The lapels and epaulettes are self material and more notably, it has a single-breasted effect (The front buttonholes are false).
It originally came without buttons attached; having eyelets where they were meant to go. I bought those from Three Feathers Pewter. Unfortunately, no waistcoat was included, but I can wear it with a black or white evening waistcoat I already own.

Here is the front and rear:




There's a bit of history to it with the owner's name and the year 1935 on the label. It would make for interesting research. He was obviously a military man based on the loops on the lapel for a medal bar.



For the tidy sum of £26 I really struck gold. It was made by Meyer & Mortimer and obviously bespoke. It really is in outstanding condition at 77 years old. There's only moth-hole on the cuff and the silk cording on the tashes had partly come loose. It's made of rather sturdy barathea or twill with a quilted lining.

More importantly, it literally fits me like a glove! There is no size on the doublet itself but the listing described it as a 38" chest, which I am. The height is perfect with the body (above the tashes) ending at my waistline. Worn with a waistcoat it's rather snug, with the edges barely touching. If anything, the sleeves are rather long, ending almost at my knuckles.

Obviously, it should more than do the job more black-tie; or white-tie functions for that matter.
Here's the catch though; can it pass as Highland morning wear? It bears passing similarity to a black Argyll; and I thought it might do the job were I to swap the buttons for bone or leather ones, and team it with a day waistcoat.

Has anyone ever seen, or owned, a doublet of this sort? Or for that matter, whether something this unique is still produced? It doesn't look like something you can easily purchase off-the-peg, and the fact that it detracts from the whole cookie-cutter look really appealed to me. Because I'm quite ready to spend a fortune on Highland wear I really was quite lucky.
