Could be WW2 or put together later

The Paratrooper insignia, marked "TOBIE OJCZYZNO" (screw back marked Kirkwood & Son Edinburgh) is not numbered

The Glider badge (screw back marked Gr. Techn. London) is attached to the lower right sleeve

Plenty of pics so you can decide for yourself

There was once a trapezoid badge on the left upper sleeve which has been removed (see photo 5 & 6 showing outside and inside of sleeve)

One repair to the right sleeve near the elbow
