B134 and B135 are recorded as alternative funnels. From 1942 Talbot-Booth narrows B135’s band and adds B533 as another alternative, repeated in 1944 with flag versions. Earlier Talbot-Booth entries specify no flag.
Merchant Ships 1949 gives B133 and B537 as alternatives.
Brown 1951 and 1958 print “JHB” in error; the 1958 notes correct the letters and specify a swallowtail rather than that edition’s rectangle. Stewart and the 1966 Liverpool Journal of Commerce chart also show a rectangle. The WSS history and National Maritime Museum support B133, but Rosanoski records continuing uncertainty over the correct version. The flag presumably ceased with the 1964 sale, although a 1967 book still gives the old Billmeir funnel.
