Antique 1795 THOMAS WEAVER Unframed Canvas BULL Oil Painting

Thomas Weaver (1774 - 1843) was active/lived in United Kingdom. Bull painting on stretched canvas and wood exposed at back. While I can not find a signature on the painting, scratched into the bottom frame slat is “By Weaver 1795”. 
This is an early painting for Weaver, but I am certain it is his. 

Measures 24.25" x 18.25". Recently had light restoration and was cleaned.

Biography from Dreweatts & Bloomsbury Auctions:
Thomas Weaver was born in 1774. He was a Shropshire artist who mainly painted portraits of livestock for their breeders. He was given some instruction in painting by John Boultbee, whose work, in turn, was somewhat influenced by Stubbs.

By 1800, Weaver had a thriving practice as a livestock painter. He began working for William Coke of Norfolk, and many of the leading agricultural reformers.

Weaver's paintings include The Warwickshire Hunt and its Master John Corbet , of 1812, and also a series of horse paintings in 1815. He exhibited at both the RA and the Liverpool Academy.
