Hi Bruce,
Congratulations with your new sword. It’s a nice sword. I don’t have Dawson's book but what is the story about this type of sword? Why is the blade chrome plated? I can’t figure out why. Protecting the blade with oil should be enough. Also, the chrome hides all the beauty of the blade and it’s no longer possible to sharpen the blade. This makes it almost useless.
It could be chrome plated post-war. Dave already mentioned this option. I have seen a lot of bayonets threated this way, all post war.
Regards, Ed
