A well made V spring is undoubtedly a thing of beauty. Personally I find the encased coil springs in the Fratelli Gambas rather beautiful too.

It has crossed my mind that V springs probably were favored in early gunmaking because they could be made as and when needed on the premises. Coils are more of a specialist high quantity item, not so practical for low production guns.

That Ugartechea with coil spring shows a better finish than any Ugartechea I have ever seen. Which goes to show that coils can be part of a well finished total.
