These guns are also called wall/rampart guns. These massive guns essentially filled a gap between rifles/muskets and artillery. These guns are quite rare today, especially in the public market. The barrel has London commercial proofs and a rounded front sight blade. The lock has the East India Company's rampant lion trademark and double border line engraving. The brass furniture also has border engraving, and "No 4" is inscribed on the trigger guard bow. The stock has a hole for a yoke.
