This is one form of Panchayatna Vigraha. From the top left corner: It is Ganesha riding his Vahana( a rat), Linga (the aniconic form of Shiva) protected by a Cobra, A goddess (possibly Parvathi), standing Nandi, Sun and Crescent moon, Homa Kunda (?) in the shape of Chauksi (Ludo kind of game), and a heap of five spheres occupy the elevated platform. See the photo below for the last two items.

It is the heap of five spheres that identifies this bronze as a Panchayatna Vigraha.

To paraphrase ” The heap of balls, on our left, are five in number. This may represent five major deities Vishnu, Siva, Ganesha, Shakti and Sun. This representation is common in Central India. The five stones, believed to be permeated by the five deities, are arranged in five different ways depending on the particular deity being worshipped.”  This narration is based on Monier Monier-Williams’s book on Religious Thought and Life in India pages 411-412

On this blog site, there is one other Vigraha with a heap of five balls, Govinda Bhairava.

This is a robust bronze. The Vigrahas are made of copper-rich alloy and the base, designed for a swing, is made of brass. In addition to the four loops, the platform has legs. The length of this bronze is 8.5 cm and the depth is 7 cm.

The Vigraha has seen a fair amount of worship, as evidenced by the wear. This may be dated to the early nineteenth century.

Some people categorize this as a Ganga-Jamuna type due to the use of two alloys.

Note 11 July 2022: For some reason, the Pachayatna blogs raise a lot of questions/exchanges. Most of it appears to be related to the way deities are represented in the Vigraha. Here is a definition from one of my go-to books Iconographic Dictionary of Indian Religions by Gosta Liebert.
