Jean-Baptiste was the father of Lucien & Oscar Delcour and had been a manager for Pieper & Cie before opening his own shop specializing in Damascus barrels. He received a patent for SxS barrels in 1910.

August 7, 1914 Liege fell to the invading German army. Damascus production soon ceased.

Canons Delcour S.A. was registered in 1921, and remained in business until about 1968 when they were acquired by Fabrique National de Herstal.

In 1924 Delcour-Dupont attempted to revive Damascus production in Nessonvaux. According to Puraye, the last barrels were made in 1930.
