The Leighton Buzzard NG was one of several that went to the sugar mills of India after the war. Baldwin 45380/1917 is stored at the now closed BSSC Hathua Sugar Mill in Bihar, India; and 45231/1917 is stored at the closed BSSC Motipur Sugar Mill in Motipur. Colin Garrett took several pictures of these engines while they were still in service.
Another one was reported at a sugar mill in Jawan; but that one may be a duplicate of the above two. Finally, Baldwin 45010/1917 is derelict at a depot in Volos, Greece.
With the two in the UK and the one in Australia; that makes 6-7 thought to still be in existance.
