One thing you can see from this clip is that it was taped after The Shadows entered the JMI deal for loan-guitars (Jet is playing the red bass adorned with his initials), which casts doubt upon the usually-supposed date some time around the spring of 1961. Hank is still playing 34346.
The website
http://www.cliffrichardsongs.com/crseries/ indicates that these shows were taped by ATV in January 1961 for transmission over the following ten or twelve weeks. How reliable that is is anyone's guess, but it makes some sort of sense because of that mixture of guitars, still involving the 1959 Strat but also a new FR bass and the blonde Telecaster (or perhaps "one of the blonde Telecasters").
Bruce' does seem to have been fairly promiscuous in his use of electric guitars around that time: he was photographed with, and seen using, the sunburst Jazzmaster, his orange Gretsch 6120, the blonde Telecaster and the red R/N Strat delivered in the spring of 1961.
