From Peter Laidlers book on the subject, the Savage rifles were shipped to Englandfor H&H conversion - however the rifles did not meet the specifications and extra work had to be done (including changing the barrels to 'in-spec ones') This meant that the time spent was not 'worth it' so, as BSA had increased productoon and were supplying sufficient numbers of 'in spec' rifles the Savage ones were put into stock (just in case BSA got bombed) which is why there are so many 'Savage No4T unfinished and without scopes' floating about. (Some of which have been civilian fitted with scopes and sold as pukka 4Ts)
