From British Single Shot Rifles (Wal Winfer & Tom Rowe) Volume 7 page 92…….”Thirty caliber Whitworths are extremely rare, with only about 5 known. They were probably made on an experimental basis as this small a bore with Whitworth rifling must have given serious fouling problems. The rifle a higher grade bar action slidelock with a four pin bridle for internal parts attachment. Sparsely engraved, the locks show Joseph (later Sir Joseph) Whitworth’s wheat sheaf trade mark. Amongst other achievements, Whitworth was partly responsible for standardizing the coarse thread system in Great Britain which even today bears his name.”
