Harrods Patience Puzzle

In addition to their own, highly popular red-boxed Zag-Zaw puzzles, Raphael Tuck & Sons Ltd., also produced a range for Harrods, London's most exclusive department store.
These are considerably scarcer than Tuck's own range and were either supplied in pale pink boxes, most of which now faded to a creamy-white, or blue boxes, as in the case of the exceptional puzzle Changing Guard at St. James' Palace.
The examples I have seen so far are cut in the earlier, non-interlocking style, so this range probably date from the early 1920's -1930's.
Catalogues of the puzzles available were produced, but as yet I have not managed to access one.
Please let me know if you have any literature available. Thank you.
