Three markers that cluster firmly in the wartime substitution era. France entered the Second World War with a fountain pen industry built on celluloid, gold, brass, and rolled-gold trim. By 1940 those material lines started closing. Gold was redirected to currency reserves, brass to munitions, and several smaller French ateliers shifted to materials outside the regulated chain for both nib and body. Glass nibs appear on this kind of production across Continental Europe through the war: Goldfink, Columbus, Burnham, and a long tail of unbranded German, Italian, and French makers all used them as ersatz tipping when gold became unobtainable. Aluminum followed the same logic for bodies, in the same year (1941) S.T. Dupont turned to aluminum for its first lighter when brass became strategic.\u003c\/p\u003e\n\u003cp\u003eThe body here is solid aluminum, not an overlay over hard rubber. Chased waves run the length of the barrel and cap, the kind of decorative work that gives an otherwise functional wartime pen some visual life. The aluminum gives the pen real weight in the hand: 26.3g capped, with a girthy 8.78mm grip and 118.83mm capped length. Substantial without crossing into heavy, in the register of a metal-overlay Waterman rather than a celluloid lever-filler. Nickel-plated trim throughout, button-filler mechanism. The maker is unsigned. Unbranded French production was common under the Occupation, with smaller workshops continuing to assemble pens from available materials without registered names on the barrel.\u003c\/p\u003e\n\u003cp\u003eThe clear glass nib lays a controlled 0.40mm line, single width with no variation under pressure. Glass nibs work by capillary feed along spiral grooves cut into the tipping, with ink running down those grooves to the page rather than between flexed tines. The result is a smooth, rigid writer with manifold character: a precise, dry-leaning line that holds across long writing sessions without skip or hard start.\u003c\/p\u003e\n\u003cp\u003eGrade B-. The aluminum carries microscratches from a previous life of carry, intentionally left in place. Polishing the surface flat would remove the patina that gives the pen its honest vintage character and risk losing detail in the chased waves, glass nib inspected for crack-free condition and seated cleanly in the section. Fitted with a latex sac, but can swap to a silicone sac if you want to use more diverse and troublesome inks (remember silicone sacs will creep ink so keep pen upright in storage).\u003c\/p\u003e\n\u003cp\u003eTested on Rhodia 90gsm ivory with Pelikan 4001 Brilliant Black.\u003c\/p\u003e","brand":"Heron's Mooncake","offers":[{"title":"Default Title","offer_id":46860418056380,"sku":"HM2605008","price":350.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0740\/7435\/7948\/files\/DSC02739.jpg?v=1779484831","url":"https:\/\/heronsmooncake.com\/products\/french-chased-aluminum-button-filler-npt-glass-nib","provider":"Herons Mooncake","version":"1.0","type":"link"}
