Questions with purchasing vintage Straight Razor

[esp]

Well I already am interested in purchasing a vintage Straight Razor.I have a few questions.

Before I purchase a vintage razor how do I know what can be restored and what can't? and to what degree?

I would be sending out the vintage razor for a full restoration.

I would rather buy from this boards classified section but am limited.

Do people post ebay links of what there interested in buying and does this board give feedback on the potential purchase? Or do I send the link to a person who I want to restore it so they can see what I'm interested in?

Also who are the top people to have the razors sent to for a restoration? Sites?
