I've read that the Patchett submachine gun was used at Arnhem
Witch troops used them & is there any photos

It appears that 120 prototypes were made and a few were used by Airborne troops at Arnhem and afew elsewhere. It eventually became the "Sterling".

"The Sterling Engineering Company made their start in firarms by manufacturing the Lanchester submachine gun for the British Navy in World War 2. They then produced prototype models of the Patchett submachine gun and eventually adopted the gun as their own, producing it as the Sterling. The company is now known as the Sterling Armaments Company.
Manufactured by Sterling Engineering Company in the United Kingdom."

Here is a Sterling or Patchett gun.
It was developed by G.W. Patchett towards the end of WW2 at Sterling Engineering Company of Dagenham in Essex. 1951 it was adopted and delivered in 1953 as Submachine Gun L2A1. Sterling was adopted by New Zealand, Canada, India and several other countries in the Commonwealth beside from UK.
There is a silenced version of this gun called L34A1.
