Can anyone date this interesting James Dixon Coffee Set?

[SimonWS]

Hello… I have this 4 piece James Dixon EPBM Coffee Set. Although I’ve done my own research in unable to find another example the same as this… can someone help give an approx date for these and a name for the style? And an approximate value would be very appreciated!

And has anyone been able to figure out the alphabetical dating system JD&S appears to use? These all have an Upper Case ‘K’.

Also… am I kidding myself, or are these all hand engraved??

I don’t think Dixon ever used a date-lettering system. The K probably refers to something else, whose meaning is lost in the mists of time.

The irregularities in the engraved design do suggest that it was done by hand.

Thank you Jeff… much appreciated!
