Jain Tirthankara you may already know this but....

[VisualThinker7@zzzzzzz]

A  Tirthankara  is a person who has reached spiritual  perfection, in the
Jain religion; rather like a Bodhisattva in Buddhism.

If an image of that particular sculpture isn't available from the Museum,
there may be a photo of it in a book about Jain art, or Indian art, or you might
 even find a photo of it mis-attributed to a Buddhist artist. I've seen
sculpture  described as Buddhist when it was nothing of the sort. This became more
common  when Buddhism became fashionable again a few years ago.

There are many different sculptures of Tirthankaras, the search could be
exhausting. As far as I know, modern artists continue to produce these works, as
commissioning works of art and building temples continues to be a highly
valued expression of devotion among believers.

PS
The owner of my local newsstand is a Jain. I found this out when I  asked him
what he was eating one day, as I bought a newspaper. In the course of  our
conversation I told him that his dietary practices sounded Jain to me and he
was astonished that I'd even heard of his religion.
