French 37 mm Trench-Art Cartridge Assembly, CUIRE — Scholarly Analysis
Extended scholarly study of "French 37 mm Trench-Art Cartridge Assembly, CUIRE" (accession JCA.2026.082): material analysis, authentication methodology, comparative works, and bibliography.
Extended description
JCA.2026.082 combines a French 37 mm cartridge case and seated projectile with hand-worked trench-art decoration. The case is recorded at approximately 6.5 in. high and bears the headstamp elements “37-85,” “P.D.Ps,” “70 10 14,” and a flaming-bomb/proof device. The body has a punched or stippled ground around the raised word “CUIRE.” The current catalogue reads the case date as October 1914 and places the decorative conversion in the wartime or immediate postwar period. The military case and the later decorative intervention should be treated as two distinct chronological layers.
Technical analysis
The “37-85” marking is consistent with surviving French 37 mm Hotchkiss/Mle 1885 cartridge cases. The Australian War Memorial holds a 1918 French example marked “37-85,” “PDPS,” a production/date sequence and a French exploding-bomb cypher. That close headstamp structure supports the identification of JCA.2026.082’s case as period French 37 mm ordnance. The exact meaning of every number on the JCA case should be documented from a perpendicular macro photograph rather than inferred. The projectile/nose is open or lacks its fuze, and inert status has not been professionally certified.
Authentication methodology
Authentication of the case rests primarily on the headstamp system, dimensions, brass case construction and period-comparable markings, not on patina alone. The decorative work should be assessed separately through tool marks, wear across punched surfaces, deformation and the relationship between decoration and existing corrosion. Before any handling beyond normal display, a qualified ordnance specialist should confirm that the assembly is inert; visual appearance, an absent fuze or an altered primer is not sufficient safety certification.
Comparative works
Australian War Memorial object REL33399 is a French 37 mm Hotchkiss cartridge case made in 1918, marked “37-85,” “PDPS” and a French exploding-bomb cypher. It provides a strong institutional comparison for the military case and headstamp family, but not for the JCA object’s hand-worked “CUIRE” decoration or its individual history.
Provenance
No documented ownership or find provenance accompanies the object. “CUIRE” is an inscription on the transformed case, not a proven findspot. It may refer to Cuire / Caluire-et-Cuire or to another personal or place association, but no documentary link has been established. No specific battle, soldier, workshop or battlefield recovery should be assigned.
Historical context
Spent or surplus cartridge cases were frequently transformed into commemorative, decorative and utilitarian objects during and after the First World War. “Trench art” is therefore a useful collecting category but does not by itself prove manufacture in a front-line trench or by a soldier. JCA.2026.082 is best interpreted as a period military material object that was subsequently individualized through hand decoration, with the maker and circumstances unknown.
Conservation history
No formal treatment history is documented. Do not polish the brass, remove dark corrosion, deepen the punched decoration or attempt to remove the projectile. Preserve the headstamp and “CUIRE” surfaces with high-resolution photography. Because inert status is unverified, conservation handling should follow qualified ordnance guidance before any disassembly or internal examination.

Further manufacturer-level interpretation of P.D.Ps and the numeric sequence should remain provisional until a clear base macro is reviewed.
