Nibs from this window — sometimes called \"later 1950s\" factory grinds — are highly regarded by collectors for their exceptional softness and expressive character relative to their nominal grade. A factory Fine from this era does not write like a modern Fine; it writes closer to an EF in line width but with a springiness and responsiveness that modern nibs do not replicate.\u003c\/p\u003e\n\u003cp\u003eNotably, this pen retains the early telescopic piston mechanism, placing it toward the earlier portion of this production window — likely 1955–1956 — before Montblanc fully standardized the simplified piston assembly across production. The telescopic mechanism is mechanically elegant and functions reliably when properly sealed, but it is the detail that separates the earliest 146s from all subsequent production.\u003c\/p\u003e\n\u003cp\u003eThe body shows honest wear consistent with decades of use: minor wear to the gold-plated trim and rear finial, and a degree of barrel transparency caused by celluloid thinning in high-contact areas. This is a natural aging process in celluloid material and does not affect structural integrity. The ink window remains fully transparent and the ebonite section is in excellent restored condition.\u003c\/p\u003e\n\u003cp\u003e🧪 \u003cstrong\u003eQA \u0026amp; Recommendation\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eAt 300g, this is a clean butter flex — soft enough to produce meaningful line variation with light intentional pressure, firm enough to write comfortably as a daily pen without babying. The hairlines are genuinely fine, almost EF territory, and the flex strokes land at a solid broad that adds real character to everyday handwriting without demanding calligraphic technique.\u003c\/p\u003e\n\u003cp\u003eThis nib rewards a relaxed grip. It does not need to be pushed — held at normal writing pressure it lays down a clean, consistent EF line; any additional intention in the downstroke immediately opens the tines toward 4B. Snapback is crisp with no hesitation. The flow is well-balanced for Pelikan 4001 and comparable inks, with no skipping or hard starting observed across extended writing sessions.\u003c\/p\u003e\n\u003cp\u003eThis is an ideal entry point into vintage 146 flex writing. The grade B condition reflects honest age and wear, not damage, and the nib performance is fully uncompromised. Recommended for daily writers, intermediate flex users, and anyone wanting a workhorse vintage Montblanc at a grounded price point.\u003c\/p\u003e\n\u003cp\u003eTested on Rhodia R 90 gsm with Pelikan 4001 Brilliant Black.\u003c\/p\u003e\n\u003cp\u003e🔧 \u003cstrong\u003eRestoration Commentary\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eCrisp model number and nib imprints on piston knob; minor wear to gold-plated trim and rear finial consistent with age.\u003cbr\u003eBarrel shows light transparency at high-wear contact areas — inherent to aged celluloid, structurally sound.\u003cbr\u003eInk window fully transparent.\u003cbr\u003eBlack ebonite section rejuvenated and hand polished, \"softness\" of ebonite restored.\u003cbr\u003eCoated with carnauba wax to shield from moisture, UV, and celluloid crystallization.\u003cbr\u003ePen fully disassembled and cleaned thoroughly, with new piston seals installed and lubricated.\u003cbr\u003eNib heat set and tuned for smoothness.\u003c\/p\u003e","brand":"Heron's Mooncake","offers":[{"title":"Default Title","offer_id":46088634138812,"sku":"HM2602010","price":900.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0740\/7435\/7948\/files\/DSC01637Large_3ca98fc4-9681-4299-a29b-78a83ab87855.jpg?v=1774184423","url":"https:\/\/heronsmooncake.com\/products\/montblanc-144g-black-celluloid-gpt-4-14c-flex-ob-copy","provider":"Herons Mooncake","version":"1.0","type":"link"}
