VACUUM-FIL was intended for the initial release of the Sheaffer version of vacuum filler. The first Sheaffer Balance with a vacuum filler appeared in the 1935 catalog. VACUUM-FIL renamed the WASP Pen Co in 1936.\u003cbr\u003e\u003cbr\u003eThis is the largest VACUUM-FIL \/ WASP pen made; collectors call it OS or Oversize. This is probably a second generation pen. The first generation pens have fat, 1\/8\" (3.175 mm) filler rods. The second generation pens have the same 5\/64\" (2.07 mm) rods used on the later Balance pens. I have replace the original rod with a black oxide coated stainless steel rod. The original was celluloid covered carbon steel. Those often fail when moisture gets beneath the cover and the rod rusts. This stainless rod will last the life of the pen.\u003c\/p\u003e\n\u003cp\u003eThe nib is soft, bouncy, wet and an amazing writer. I hesitate to describe it as semi-flex because these nibs are 12 karat gold and quite thin. They provide lovely line variation under normal writing pressure but should never be pushed like a truly flexible nib.\u003cbr\u003e\u003cbr\u003eThe cap band and clip ball have areas of plating loss. The transparent barrel has darkened a bit from its original pale green. The celluloid has no damage at all.\u003cbr\u003e\u003cbr\u003eLength\u003cbr\u003eCapped - 128 mm (5.1”)\u003cbr\u003eUncapped - 119 mm (4.7”)\u003cbr\u003ePosted - 150 mm (6”).\u003cbr\u003eDiameter\u003cbr\u003eCap - 13.3 mm (0.53”)\u003cbr\u003eBarrel - 11.5 mm (0.44”)\u003cbr\u003e\u003cbr\u003eFiller\u003cbr\u003eVacuum-Fil\u003cbr\u003e\u003cbr\u003eNib\u003cbr\u003esoft fine\u003c\/p\u003e","brand":"Paper Wants A Pen","offers":[{"title":"Default Title","offer_id":48687022899394,"sku":null,"price":475.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0273\/7055\/3441\/files\/PXL_20260826_205640430.jpg?v=1787798862","url":"https:\/\/paperwantsapen.com\/fr\/products\/1934-5-large-oversize-marine-green-vacuum-fil-soft-fine-point","provider":"Paper Wants A Pen","version":"1.0","type":"link"}
