Nice level George. It appears pristine.
I use WD40 for removing those pesky labels. It is generally not harmful to plastic or painted surfaces and it doesn't have the obnoxious smell of the solvents. It doesn't dissolve the rubber based adhesives but softens them enough to wipe them off easily. Remove as much of the label as possible for quicker action. Other light oils or mineral spirits will also work although, in my experience, not as well.
