+++1 on the previous posts...You have an excellent vintage razor there. Don't take it to a knife sharpener to get it honed. I wouldn't even get the scales replaced. They can probably be restored along with the blade.

Check the SRP "Classifieds." There ought to be a str8 razor restorer, such as Maximilian, who would be more than happy to hone and restore your find to its former pristine beauty.

BTW...That's a beautiful razor. In fact, if you follow this link you will see what it would look like completely restored.
