Many electrolytic will have a date code, such as 09 71 (week 09, in 1971). The cabinet may also be stamped internally with its date of manufacture. The later yellow coloured axial Plessey/TCC paper dielectric capacitors and their successors (in grey plastic) will also have a date code, as per the above.

I don't think Thorn applied a date code to the chassis, just a Schedule letter, to indicate production modifications.
