Original Imperial German Kaiserliche Marine (Imperial Navy) officer's white tropical and summer-service uniform (weiße Tropenuniform / weiße Sommeruniform), comprising the tunic with both original shoulder boards in place and the matching white cotton trousers, attributed by period handwritten name tape inside the collar to an officer surnamed Steinmüller. The set is the standard regulation pattern for Imperial Navy officers in tropical postings and home-water summer service from the late nineteenth century through the close of the Empire in 1918.

 

The tunic is constructed of white cotton drill (weißer Drillich) in the regulation cut: high stand collar (Stehkragen), single-breasted front closed by a row of gold crown-and-anchor buttons, single right chest pocket with rectangular flap, two lower hip pockets with rectangular flaps, plain rear with center seam and characteristic short skirt. The buttons are the regulation Imperial Navy pattern in gilt brass, struck with the Kaiserkrone über Anker (Imperial crown over anchor) — the design used by the Kaiserliche Marine throughout the Imperial period and replaced after 1918 by the simplified anchor of the Reichsmarine. All visible buttons appear intact across front, pockets, and shoulder-board mountings.

 

The shoulder boards (Schulterstücke) are the original pair, mounted to the tunic and present on both shoulders. Each board is constructed in the regulation Imperial Navy subaltern-officer pattern: two thick silver-bullion Doppelflechte (double-braid) cords laid side by side and worked into the characteristic interwoven flat braid, finished with rounded outer ends and seated on a dark underlay in regulation Navy backing color. The inboard end of each board is closed by a small gilt button stamped with the crown-and-anchor device, matching the front buttons in pattern. No rank stars (Sterne) are visible on the boards in the photographs, which on the Imperial Navy system would identify the wearer as a Leutnant zur See (the most junior commissioned officer rank, the equivalent of a sub-lieutenant or ensign); a buyer in-hand should verify the upper surface of each board for any small applied silver star, since the rounded-end Doppelflecht construction was shared by Leutnant zur See, Oberleutnant zur See, and Kapitänleutnant, distinguished only by zero, one, or two stars respectively.

 

The interior of the collar carries the original sewn-in name tape with the handwritten attribution Steinmüller in period black ink script, indicating that the tunic was personally tailored or fitted to an officer of that surname. The script is in the careful hand typical of tailor-applied or batman-applied officer name tapes. Steinmüller appears in the published Rangliste der Kaiserlich Deutschen Marine across multiple years of the Imperial period, and a buyer with access to the year-by-year Navy lists may be able to fix the original wearer by cross-reference of rank and service period.

 

The matching white cotton drill trousers are the regulation Imperial Navy pattern: high waistband with internal cloth back-belt drawstring tabs for adjustment, button fly, side hand pockets, single rear flap-pocket, and straight legs with plain hems. The construction matches the tunic in cloth weight, weave, and stitching, and the trouser buttons are the small white-metal cotton-twill type used on Imperial Navy white trousers throughout the period.

 

The Imperial Kaiserliche Marine white tropical uniform was the regulation summer-service dress for officers on warm-weather duty across the Imperial Navy's global presence — the cruiser squadrons of the East Asia station based at Tsingtau (Kiautschou) in the German leased territory of Shandong, the West African and East African stations supporting the German colonial possessions in Deutsch-Südwestafrika and Deutsch-Ostafrika, the South Seas squadron supporting the German Pacific colonies, the Mediterranean and Eastern Mediterranean visits, and home waters during the summer months. Officers serving on ships in tropical waters wore the white uniform as standard daily and watch dress, switching from the dark blue Imperial Navy frock coat (blauer Waffenrock) only for cold-weather operation or formal occasions ashore. The cut described here was standardized by Navy regulation in the 1890s and remained substantially unchanged through 1918.

 

Condition is honest and consistent with a piece that saw period service in tropical climate followed by long storage. The white cotton retains overall structural integrity with the expected yellowing and ambient staining typical of long-stored Imperial-period white cotton uniforms — the discoloration is uniform rather than concentrated, characteristic of natural aging rather than active soiling, and is largely consistent with the way these uniforms appear in surviving examples that have not been aggressively laundered. Both shoulder boards are present, with the silver-bullion braid sound and the small crown-anchor buttons original and seated. The tunic shows a small clear hole or two on the chest panel visible in the close-up photograph, along with light overall yellowing; the trousers show similar yellowing and some scattered light staining without holes or seam separation. All front, pocket, fly, and shoulder-board buttons appear original and present. The collar lining shows wear typical of long contact with skin and sweat. No alterations or post-period replacements are apparent.

 

Imperial Kaiserliche Marine officer uniforms are among the most actively collected categories of Imperial German militaria, and within the Navy category the white tropical sets are noticeably scarcer on the market than the standard blue dress uniforms — most surviving Imperial Navy white cotton tropical garments did not weather a century of storage as well as the heavier wool blue tunics, and complete sets with both shoulder boards present and a named provenance are a small subset of the surviving population. The piece carries direct connection to the colonial-period operations of the Imperial Navy, suits collectors of Kaiserliche Marine officer kit, colonial-period German material, and Tsingtau / East Asia Squadron grouping, and fits naturally into a naval-emphasis grouping or a German-colonial-period display.
