Just to shed a little light on information i have.
Home Office Circular 176/72 (Firearms for Police use in Peacetime)
dated 29th September 1972

Quote>>> The working party recommend the L39A1 rifle, fitted with the two piece telescope mounting and Pecar V2S telescope.
It will be manufactured by the Royal Small Arms Factory at Enfield and sent to
Messrs Parker Hale Ltd. in Birmingham for a suitable stock to be attached, for the telescope and mounts to be fitted, and for other minor modifications.

So reading this i think they went to Parker Hale without the wood,....
But hey ! who knows what really happened.

when i was in the army i thought we would be fighting russians!!!!!!

I will try and locate a scanner and scan the document and post it
