I sold an eyedropper pen recently with Mabie Todd’s version of the spoon feed, not unlike Waterman’s and equally efficient. Though Mabie Todd experimented with the over-and-under feed and improved it over the years, the spoon feed was noticeably better, giving good ink delivery. It was also much less likely to drop a blot.
Good though they were, those feeds were not produced for long. Mabie Todd’s R&D came up with the superior ladder feed, so good that it lasted as long as the company.

Pity no photos of comparative feeds..
Wow! I’m overwhelmed by your gratitude! Just because a subject comes to mind doesn’t mean I have examples to hand. But that’s okay, I’m sure you’ll find another 11-year-old blog that does things better.
Hi Deb—
Congratulations on your 11th year of this blog! The vast majority of us (>99%) enjoy reading, sharing, and learning from your posts, although there are a few “Dimwitted” individuals who don’t seem to know how to be polite in the real world. But as with any population of “n” individuals, there are always a few outliers.
Pity you don’t have one of these on your keyboard.
Thanks again for your posts and stay safe and well in these uncertain times.
True, James. A “smite” key would be very useful!
Thanks for that – it was interesting and it started me off on an enjoyable ramble round the internet!
Thank you, Anne. It’s always a pleasure to spread interest in these marvellous pens.
