Parts Envelope Stamped “Peenemünde” and “Fl. U.V.,” with Five Slotted Metal Tubes.

A small brown paper parts envelope, ink-stamped “ggk” and “45” near the top, rubber-stamped “PEENEMÜNDE” diagonally across the face, and stamped “Fl. U.V.” near the bottom, kept together with five slotted, thin-walled metal tubes roughly 45mm long — a length that happens to match the envelope’s own “45” mark, though nothing confirms the two are related.

“Fl. U.V.” turns up on dealer listings for Luftwaffe canteen cutlery and crockery as short for Flieger-Unterkunft-Verwaltung (Luftwaffe accommodation administration), which would place this envelope with the Luftwaffe’s Erprobungsstelle Peenemünde-West — the site that tested the V-1, the Me 163, and similar weapons — rather than the Army’s Heeresversuchsanstalt represented elsewhere in this collection by the Heimat-Artillerie-Park 11 badge; that expansion, though, rests only on dealer sources, not an official wartime abbreviation list.

Peenemünde-West began operations on April 1, 1938, and the Soviet occupation of the whole site in May 1945 sets the outer date.

What the tubes themselves were for is not established: they resemble a standard slotted spring sleeve, but that identification is unconfirmed, and small parts envelopes of this kind were commonly reused, so their being kept together is not proof the envelope and tubes originated together during the war.
