Rod, is the page you posted from Billig's Vol. 40, sub-vol.III?
Eric, sorry no idea at all.
It was sent to me on 1st February 2008 as part of study fellowship.
From whom I cannot recall.
It in inspired me to save one day for a Billigs set (c$1,200)
If the Billigs you are looking at has "India" then I would suggest that is the one, but certainly ask the vendor.
There are differing editions of Billigs also, I believe.
The unknown, above, I keep a scan with the available text string,
in this case ANAGHU then as more examples come to light, I can search for text strings that match.
