From the pictures I saw, their firefighters also have equipment that looks like it is from the beginning of the 20th century, starting with their helmets.
I noticed that too, not from the beginning of the twentieth century but certainly the helmets reminded me of what UK firemen used to use up until about the mid-eighties.
Those old black Bakelite helmets, the big heavy “donkey jacket” style tunics and rubber wellington boots were certainly reminiscent of old British firemen’s uniforms, no doubt the Brits sold off all their old stock to the Indians along with the old tin helmets that most of the soldiers seemed to be wearing.
