Late 1800's sewing machine cabinet

This is a late 1800's Wheeler & Wilson #9 sewing machine cabinet. Singer Corporation took over the Wheeler and Wilson Manufacturing Company in 1905. Singer continued to produce the Wheeler and Wilson #9 model sewing machine under its own brand name until at least 1913. Even without the sewing machine I still love the cabinet itself. It even still had 1 spool of blue thread in the drawer. I bought if for $30. Maybe I'll make it my first restoration and use it as a beautiful desk. Any recommendations on the type of oil I should use on the wood and iron would be greatly appreciated. Thank you!
