Frankenstein doublet?

[blackwatch70]

There is a strange military doubet on ebay just now:
https://www.ebay.co.uk/itm/Queens-Ow...97.m4902.l9144

It is marked as Queen's Own Cameron Highlanders - Officers No1 Dress Doublet, but I strongly doubt.
First of all, this style of green doublet with skirts was worn not officers but pipers.
But this particular doublet has officers gauntlet cuffs with gilt braid edging, probably original brass Queen Own Cameron Highlanders buttons , but AA QoH buttons on new shoulder boards... I think SB were added a bit later. Correct QoH collar badges (originally Seaforth), and - interesting! - visible collar holes probably from old different regimental collar badges!

It has probably original label of Major A.W.J. Angus, Sept 1953, but I doubt that Queen Own Cameron Highlanders Officer wore this doublet.

What do you think about the doublet?

Moreover, same seller sells another "Queen's Own Highlanders - Officer's No1 Dress Uniform Doublet" (https://www.ebay.co.uk/itm/Queens-Ow...UAAOSwdstfsrzs), which in fact is not a doublet, but a QoH officers coatee, this time it looks absolutely correct.
