This is a Mabie Todd Swan Safety Screw Cap eyedropper fountain pen which has both cap and barrel gold-plated in a pattern of vertical lines and plain bands. It has a capped length of 13.3cm. As to date of manufacture, as it is an eyedropper pen I am confident that it was made prior to 1920.On the plain section at the end of the barrel, there is the imprint 'Swan Pen Safety Cap. Mabie Todd & Co. New York'. The imprint on the Medium nib reads 'Mabie. Todd. & Co. NY'. 2'. There ar...e no imprints on the cap.The pen is in really beautiful condition - quite remarkable for a 100 year-old pen. No brassing, no dings and well defined pattern and imprints. But for one or two very faint tiny scratches on the cap I would have been tempted to describe the pen as almost Mint. The nib is lovely with a slightly upturned tip.As the pen is an eyedropper, I have not filled it but dipped the nib into ink and can confirm that it writes very nicely.The box is original and in very good condition with no inkstains. You will have notice that it contains a glass eyedropper- this is not the original but a modern replacement.This is a pen which would enhance any collection and I'm sure that the buyer will be delighted with it. As always, however, a full refund will be offered if he/she is not completely satisfied with the purchase.Buyer pays postage and packing. To addresses in the UK the cost is £4.50 (Recorded delivery).
