Also known as: IOF .32 Revolver, Indian Ordnance Factories .32 Revolver, 0.32" Revolver Mk III
Overview
The OFB 1A Revolver is a six-shot, break-action double-action revolver chambered in .32 S&W Long, produced by India's Ordnance Factory Board from the mid-1990s. Its self-extracting break-open frame derives from the British Webley Mk IV pattern, ejecting all spent cases simultaneously when the barrel is tipped down. Marketed primarily to Indian police and licensed civilian owners, the lightweight handgun pairs a six-round cylinder with a rifled barrel cut with six right-hand grooves at one turn in 380 mm. The traditional DA/SA lockwork allows a long self-cocking double-action pull or a precise single-action shot after manual cocking, while fixed open sights keep the design rugged and simple.

Also marketed by Indian ordnance factories under .32-bore revolver designations (e.g. the Nirbheek and Anmol variants). Design lineage traces to the Webley Mk IV.
Background
Built on the venerable Webley break-action pattern that armed British and Commonwealth forces for decades, the Ordnance Factory Board's .32 revolver became one of post-independence India's most widely issued police and civilian sidearms, later spawning the lighter Nirbheek revolver marketed to women.
