Ivory pieces from an Indian set

Superior pieces from an ivory part set. Most probably of Indian manufacture from around 1820. The Queens are 9 cm tall. Unfortunately neither of the Kings have survived.

All pieces are monobloc, including Rooks with round bases and rectangular bodies. Turning holes can be seen in the both ends of pieces.

A similar set can be seen on the page of House of Staunton:
full set and a close view of some pieces.

Another such set was auctioned as a part of the Ettore Chiesa Collection at Christie's. See lot #90 in the catalogue.

Both these are of smaller size than my pieces.
