Note: This is not S.G. 181a and the B.P.A. Certificate rightly gives the stamp no S.G. number. It is a great rarity and the perfs. at foot (from the bottom row), the perf. 14 measurement, match up exactly with those of the #1 perf. 14, RMG "F", position 41, another stamp from the first vertical row of the sheet, which was included in the Gibbs sale as lot 1411.
