I adore all my Swedish razors, but especially the Dahlgren frameback with the brass frame. It's almost identical to your Hellberg. It's a truly superior shaver, and just a lovely thing to look at.
I can't be sure about yours, but my Dahlgren actually has ebony scales, not horn. I didn't even notice at first, but then it sunk in that the striations I was seeing were wood grain. Magnification told true. Ebony, and quite lovey.
Another note about the brass framed blades. Both your Hellberg and my Dahlgren appear to have originally been blued blades, not bright. You might keep that in mind while cleaning it.
