... I have just acquired an example of the US version of Lillicrap's Hone from a seller who bought it in India. Logic says that it shouldn't have been there, as the standard, rest-of-the-world version has an Indian patent number on it. ...
I made an incorrect assumption. Having just discovered two more variations of the lettering on the underside, this example is more likely to be an early rest-of-the-world version, and so one of the two "correct" versions for India.

Apologies for posting this query, but then I knew of only three variations in lettering.
