Vintage circa 1930s British gentlemen's linen trousers.
 
No size label or maker's mark, these were tailor made overseas for British Expats working in warmer climates. 
 
Beige linen with buttoned fly, notch at the centre back waistband, bone buttons around the inside of the waistband for braces/ suspenders.  Side pockets.  Turn ups at the hems. White cotton liners inside.
 
Some rust transfer marks at the lower leg, a few minor marks here and there. Minor signs of wear.  A mismatched button at the inner waistband.  The inner seams are raw by design and are a little frayed in places. Very good vintage order overall. 
 
Laundered.
