Hi Mike,

There are some numbers and letters on the run off that I don't understand.
The number K50014 A with NO number after the letter -- side 1
The number K50014 B with NO number after the letter --this is stamped-on side 2.
Side 1- also has etched the following:  AT then ST-A-732783-B
Side 2- also has etched the following:  AT then ST-A-732784-B
Both sides have-not sure if etched or stamped but the lettering is very fine and close together. the following: STERLING RL
Hope you can help.
kind regards
Lis Elwell

Hi Lis

As for the K50014 A/B with no number, those do come up amongst the UK first pressings.  In other records, the A&B have a single digit number following it.  The number (or lack thereof) *may* have something to do with the pressing facility or plates, but that's not confirmed.

732783 - Year + Plate/tape code
STERLING RL - Mastered at Sterling Sound, mastering engineer was Robert Ludwig (RL)
