JOHN WIGGAN, GUNMAKER TO THE ROYAL FAMILY & THE PACHA OF EGYPT, NEWARK. This was written on a sporting gun that sold in Holts in 2014. I’ve attached a link below.

The other references to WIGGAN appear to suggest a family of gun makers who signed the name WIGGIN and then it changed to WIGGAN around 1828. I have found a reference to an advert that states - WIGGIN (WIGGAN) John (1828-1858) 26 Whittall St. 1836 advertisement:

‘J. Wiggan, continues to get up, at his Manufactory, 26 Whittall-street, Birmingham, the very first double-barrelled Guns, on the approved principle, in mahogany case, complete from £20 to £25. Most excellent Gamekeeper’s Guns, warranted in every respect, and strong shooters. From £8 to £12.’
