Dear Deryck,

Thank you for contacting Mearto with your appraisal inquiry. My sincere apologies for the delay with the appraisal.

The presented object appears to be a German WWII period Mauser P. 08 Luger semi-automatic pistol. It was made in 1941 a 9 mm cal and has the common Third Reich acceptance and proof stamps. It comes with an original leather holster.
Comparable objects were recently offered and sold on the international auction market. 
This piece is in good condition and there is no serious damage visible in the images provided.
A fair market estimation would be between 1.400 to 2.200 USD.
This estimate is based on actual recent past recorded auction sales of comparable items. Retail "asking prices" can be higher and may vary.

With kind regards, 

George
