Dress up an eBay razor

[boz]

I got this razor from an eBay vendor. I think someone has tried to restore it in the past; because the area around the wedge pins seems to have file marks, the crack near the pivot pin seems to have been fixed. I want to make this razor more presentable, not new but clean. The razor may not make it to my rotation but could be relegated to a shadow box with LED lights to display it. Anyone have thoughts on shadow box display for straight razors?
1. I would like to sand the scales to minimize the file marks around the wedge pin and the scratches on the rear scales. I will probably start with 1000 grit paper. What can I use as the final polish on the scales? What can I to enhance the writing on the frond scales, gold paint? What material are the scales made of horn, bone?
2. The blade is loose should I be able to tighten up that large a blade, 7/8 by tightening the pivot pins?
3. Does the blade look like it can be sharpened? It will cut arm hair but is not shave ready. I have never shaved with nor honed a wedge razor.
