Late war unpainted M31 messkit marked HRE 44

Excellent and desirable late war unpainted/unfinished M31 messkit without any paint or finish of any kind, none was ever applied! This is a so called transitional type which features all the characteristics of the M42 messkit but is still made out of aluminium. The messkit is nicely marked HRE 44 which indicates production by Heinrich Ritter, Esslingen in 1944. Rare and desirable variant!
