Part cover franked with Pre 1921 1/4 a greenish-blue on medium wove paper complete sheet (cliché 1,2 / 3,4). Experts believe that this is Barwani's 2nd 1/4 a stamp, different from the 1st stamp (SG 1) being that the top English value tablet is not double as normally found on the 1st stamp (SG 1). Furthermore the 1st issue of Barwani (SG 1 and 2) was issued perforated whereas the 2nd issue of Barwani (SG 1a and 2ab) was issued imperf. Furthermore, the ink shades are different, the 1st stamp (SG 1) was printed in dull blue whereas this stamp is printed in greenish-blue. A single used example, a pair a cover franked with a pair and this cover are the all that are known from this issue. Arguably one of the greatest rarities of Barwani. BPA certificate (SG value £18000)
