JP were the initials of John Piggott of 117-118 Cheapside & Milk Street, London, who produced a motorcycle early in 1913.
Advertised as the "Impregnable" Motor Cycle, the machine had a 2¾ hp engine, belt drive and sprung forks at a price of £27/10/0. There was also the option of an Armstrong hub gear for £9/10/0.
The motorcycle was listed until the middle of 1914, but the outbreak of World War I stopped any further production.
The firm was best known for its automotive clothing and photographic products, which included a folding cylist roll film camera. Sources: Graces Guide, historiccamera.com
