The 42-pounder tended to come from nationally owned arsenals and gun foundries rather than the larger pool of private manufacturers. That concentration reduced the number of producers able to fill naval orders. The same state facilities also supplied the Army, fixed fortifications, and distant colonial requirements. Uncertainty over early cannon shipments to Australia illustrates how many demands had to be served from limited capacity. A gun's availability depended on interservice and imperial allocation decisions as well as the needs of an individual ship class.
