Pre war M31 messkit marked RFI 38/39 Grenadier regiment 877

Textbook pre war matching M31 messkit in very good, light used condition. The lid is nicely marked RFI 38 and the bottom is marked RFI 39 which in my opinion indicates a piece manufactured by Rudolf Fissler GmbH, Idar-Oberstein  in early 1939. The messkit features some nice period personalizations and once belonged to an Unteroffizier in Grenadier Regiment 877 which was a replacement unit for the 6. Armee after Stalingrad. Very nice example!
