This is a period correct Bakelite razor sharpener made by Sieger (indicated by a 3 ring logo inside). It has none of the usual post war markings but could still be early post war or war time. Post war ones are often sold as war time since the company changed almost nothing from the 1930s to the 1960s. It is in good condition. The main body measures about 2 1/2" by 1 1/2".
