This & the next six lots represent the entire group of 14 proofs thus identified - a remarkable achievement, although six others must have been released on one or more other occasions: see below - allowing for the first time the segregation of three separate groups of proofs, and an accurate assessment of the shades. Several of the proofs are Ex T.E. Field and James Williamson. It would be expected that they passed from Field to Jack Kilfoyle. However, they were not included in the Field auction (Nov. 1948) that was acquired intact for Kilfoyle, so Williamson must have acquired them directly from Field.The Bulletin of the Australian Commonwealth Collectors Club of NSW (Mar. 2015) contains an article about these proofs by Geoff Kellow & Arthur Gray. In addition to the 14 proofs in the Gray collection, they identified a further five examples in the Australia Post Archives, and another offered at auction in 1975 that seem to complete a total series of 10 different colours x2 of each. In respect of the initial group, official correspondence reveals that they were endorsed a B C D and N, Gray lacking only an example of a. These were requested to be in the shades of the 6d Engraved Kookaburra, a task that Harrison found impossible to complete satisfactorily using the letterpress method. Our description of the shades is as follows, with the ACSC colours given in brackets: B in brown-purple (brown), C in a slightly warmer shade (bright brown), D in red-purple (brown-purple), and N in a slightly warmer shade (deep reddish purple). $40,00050,000'
