Hi warren, unfortunetely that does look to be another classic Indian special- all the usual hallmarks are there like you say. There’s also Lingham Brothers, Lingham Bros, Bolts & Bars escutcheon variations as well.
You’ve probably noticed when you look at any suspect plates -not just the copies supposedly of the safe makers but machinery, breweries, nautical, ships builders etc- the ones that they typically copy, they nearly always follow a similar pattern and have similar characteristics -they cast two or three versions of each with name variations, often with and without an address etc, and some in brass and others in iron. I’ve seen copies of maritime plates where almost every letter has something wrong with it- either misaligned, wrong font or actually a different size!
Also sorry to say it, but that ‘Guard’ plate you posted recently, although not as rough as others, did tbh strike me as being another strong contender :-(
