I have a very nice Majestic 72 cabinet:

I'll preserve the original finish, but it has two flaws that need attention. 
First, a piece of scrollwork is missing.  Can someone suggest what kind of wood I should use to carve a new piece?

Second, the top veneer has to be replaced.  I don't know what type of wood this is, but I have some mahogany veneer which I could use.  I've taken a small piece, stained it, and  lacquered it to see what it looks like.  Even if the grain pattern doesn't match, do you think this will look OK?

Thank you, wise ones.
