The only No8 rifles currently being disposed of are those ready for scrap due to lack of spare parts or simply worn out as in the normal course of events. There are reasonable stockpiles of No8's for those units, school CCF's and Army/Navy/RAF Cadets who still use these rifles as part of their training systems. And there are plenty who still use them in their Country Life shooting competitions.
They are still maintained and while no spare parts are being manufactured new, they will be maintained while stocks of spare parts are available by cannibalisation and existing stockpiles of spares and rifles are held.
As informed today by the equipment manager. Thanks Taff!
