Hi Roy,
They are classified as inert training non Firearms.
As they are constructed at the factory as sectioned demonstration pieces from specially sectioned components.
I purchased both from one of the largest
UK militaria and RFD's.
The London Proof House also confirm this status.
Neither have any reusable pressure baring components and are in essence 'deactivated' by design.
Of course, legal definitions of what is, or isn't a firearm, change from country to country.
From a UK perspective, if anyone is interested in this area of collecting, just make sure in advance that it's fully inert, with no pressure baring parts and most importantly, only buy one from a registered Firearms dealer, who has done all the checks first.
On these examples, the chamber's have been milled away by 50%, so they won't support an inert round, the bolt face has also been sectioned away by 50%, to show the FP channel.
