Of course, Sarma's Catalogue,

The photos I sent show an instrument imported from France to Jaipur (or somewhere in India first). It is conserved in the Museum of the Observatory.
This shows Jai Singh II's interest (or his son Madho Singh's interest) for this instrument. I have never seen any Sanskrit text on it, at least in Jaipur.
From which Arabic (or Persian) texts are the figures (of your friend) from ?

Best,

Jean Michel

That's what I suggested to him as well. I am very glad to hear you suggest something similar.

Many thanks,

The best place to look for the answer to the first question is Sarma's
incredible catalogue of Indian astronomical instruments (available here:
https://srsarma.in/catalogue.php).

It does not have equatoria as a separate category, it just lists
different types of astrolabes, but it is definitely worth a closer look.
