John COSENS
John COSENS left the London Gunmakers Company in 1662. Later he purchased Herman Barne's shop from his widow Ursula, and became "gunmaker-in-ordinary" to king Charles II, to whom he supplied a lot of pistols and one ash-stocked musket for the amount of 8 pounds, as part of a king's present to the Emperor of Morocco in 1680.
Note: The title "Gunmaker-in-ordinary" is a honour. The word "ordinary" means here that the gunmaker has become a regular supplier of the king, and not any common gunmaker. Other "gunmakers-in-ordinary" are for instance Nicolas Boutet, Mortimer, or Lepage.
