40 mm Bofors AA guns made in GB and US

[Richard Suggitt]

General update about the Bofors at The Shuttleworth Collection in the UK. ....

.... after much huffing and puffing we successfully removed the six balance springs from the gun, discovering along the way that one was broken. Our friendly spring factory says that they cannot be retempered (as they cant tell what material they were made from or how they were made in the first place), and also says that they cant make new ones using rectangular-section strip. So... does anyone know of a source of unused balance springs, or has anyone successfully made replacement springs from round section strip ?
