[7] His eldest son John Parr, born 1767, is recorded as an insolvent debtor of Elm House, ‘out of business’, by February 1840.
He may have developed his business as a gun trader and exporter, later in association with his younger cousin, John Parr of Frederick Street, the gunsmith.
In this business relationship with Farmer and Galton, he also took on the "battery trade", another aspect of the hinterland commerce dealing in small copper and brass items.
[13] The gun trade presented particular difficulties of long credit required by customers, and Galton chased Parr to collect payments.
[1] Rioting broke out in Liverpool at the end of August 1775, when sailors employed in the Atlantic trade, then in a slump, objected to a cut in wages.
[20] Commercial correspondence from 1788 mentions how Parr acquired old guns in Ireland, and had them reconditioned by workshops to be saleable in the African trade.
Galton, discussing the trade with John Mason who was in the pay of the Home Office, gave Parr most of the credit for importing Irish Ordnance fusils on behalf of the French.
