Bush MB60, TR82, VTR103 and other variants

TR82 ear phone socket question.
When exactly were these fitted as I am confused.
Was it the late MK1 that had them as this appears to be so when I read message 1.
I have done a thread on a TR82D MK2 that is fitted with the ear phone socket. It is the AF117 variant with a 349 chassis.
I am confused as to the MK that they were fitted to.

With regards the MK.I models using the A177 chassis;

TR82B (type 345) the earphone socket is absent.
TR82C (type 346) with a serial number less than around 15xxxx, the earphone socket is absent.
TR82C (type 346) with serial numbers of 15xxxx or greater, the earphone socket is present.
TR82D (type 508) the earphone socket is present.

Later when the Mk.II versions of the TR82C (type 528) and TR82D (type 530) were released using the A349 chassis, they had the earphone socket fitted as standard.
