Wow! well done you. The memory bank is well oiled.
I do not actively collect covers, so thanks but not here,
I would like to keep an image however, for my records, (with due accreditation)
Also of interest, the Bombay (Mumbai) machine cancel, what is at the bottom of the CDS (Circular date stamp) "OR"
Nice reference to the slogan "Support Indian Industries"
I did not have a clear image of that one, that was helpful.
As an aside:
The story goes something like, when Volkart bought looms and began major spinning, overnight, it killed the Swiss cottage industry of cotton spinning.
I see that as a metaphor of today's Artificial intelligence and Robots.
Note: They Perfin punctured the 2a6pice stamps, not the lowly half anna.
