Apollo Horn Gramophone

[Steve]

It's a brass horn, meant to be as shiny as a mirror. It's certainly not a crapophone so it deserves to be shone up like a new penny. If I had it the plating and horn would all be brought back to gleaming state. Its not meant to look dull, unpolished and unloved.

It certainly won't devalue it. I've got brass horns I polished to a mirror finish almost 20 years ago and they already look as dull as they did after 100 years when I first got them (assuming they hadn't been polished during their formative days).
