I would regard this with the greatest suspicion as Paul was adamant such things were never written down and kept solely and jealously in the personal knowledge of family members only., The only exception to this is the formula of Paul Ysart's Harland batch which was mixed for him by Moncrieff and this remains in the personal possession of the MD at that time who shared it with no-one.
A substantial number of such documents have circulated over the years and all were traced back to a certain Perth based dealer, who normally bundles such documents with genuine ephemera to give them authenticity. Whenever asked for provenance on such papers he backed out of the sale or further discussion. I note also labelled miniatures are included in the collection."include a yellow whorled vase with tints of white and pin, 42 MF x 1 and a turquoise green flared vase with a clear and aventurine glass rim, OOGC x 1" which sounds like similar to those in the other recent lot.
Do not be surprised to find other such ephemera, a book containing the colour formulas, several sets of 'Monart' moulds, notebooks purported to be Vasart, several sets of Paul Ysart's tools (despite the well documented purchase of the real tools.) all faked. At least one of these is probably documented on this board.
