Sieger Razor Sharpener Bakelite in Box Repaired String

This is a period correct Bakelite razor sharpener in box made by Sieger. This one appears to be war time and lacks the markings typically found on post war ones. Post war ones are often sold as war time since the company changed almost nothing from the 1930s to the 1960s. It is in decent condition with some wear and could use a cleaning. The rope pull has a extra segment tied to it where it looks like it came apart a long time ago. The box has general overall wear and staining and one side of the top and bottom is blown out and has been taped together.
