This original waistcoat from the General Post Office is a rare find for antique collectors. The piece boasts authentic buttons and is in its original form, making it a valuable addition to any collection. The waistcoat is navy and wool and the colour is good. The lining seems to be silk, there’s no sizing but it appears small to medium.
This item looks similar to this one below. I believe it’s from Tannadice Post Office, Forfar as it came with a sign I bought from there.
