I believe this is a 1922 Pattern service cap, but it’s not my area of knowledge so please look at all the photos.
Khaki service cap, with brass general service buttons, green underside to peak, and black oilcloth lining to crown and headband.
It is maker marked L SILBERSTON & SONS LTD with the WD broad arrow, size 6 3/8, and C WD 90 which I think is a date code, but not my area of knowledge, so if anyone knows the date please message me.
No mothing or damage that I can see, in fact it appears to be unissued, probably because of the small size. It doesn’t have a chin strap.
I will post this internationally by signed or tracked service.
