This is Siva, identified by the drum (right hand) and Trishul (left hand). Two-armed Siva is not uncommon, as Rudra, an earlier form of Siva, is two-armed.

He is standing in Samapada (without any bend) on a plain tapered platform. Siva is framed by a plain prabhavali. The ornaments appear to be applied rather than cast with the image.

See the back view of the depiction of his Jata, matted, braided hair. Other things to note include his tall, elongated, multi-levelled crown and long lower garment.

This is from Central India/Northern Deccan. It is about 8.3 cm in height. This bronze may not be earlier than the nineteenth century.
