Description - PM type 15 (JC) type 22 (MN) urban duplex with quite small circumference left side, and vertical oval of horizontal bars well-defined serif numeral, and larger 1 without clear inset.
PM subtype 15a – (JC) type 22a (MN) urban duplex with vertically pointing elliptical shape finer to thicker horizontal bars, within many variations of letter denoting north, south, east, west, central – denoting various districts or suburbs within Bombay city.
PM subtype 15b – (JC) type 22b (MN) urban duplex from Bombay, with small or large oval – distinguishing feature notably fine horizontal line with numeral inset only. Martin records only four numbers (p.111).
PM subtype 15 variation - Bombay City
PM subtype 15c – (JC) type 25 (MN) urban Calcutta duplex with vertically orientated oval with fines horizontal bars inset with serif ‘C’ and Bow Bazar district. Martin seems to perhaps correctly combine this 15c, where C probably stands for Central Bow Bazar No:5 District, with JC type 15d – as one of ten combinations. (see below)
