Looks like a good list Antonios, Unfortunately the espacenet site is down for maintenance right now. I'll cross reference with my list in the morning. Love those early 30's patents for the V-clips. :)

Antonios,

Thank you for so generously sharing this information. I appreciate the time and effort you put into your contributions.

I find this a very useful resource. I was pleased to see that the #444 ("hockey puck") inkwell base was one of the patents on your list. I enjoyed seeing a cross-section of its structure.

Cheers,
Laura

Thank you Dan  I appreciate your help with this one.

The thanks should go to George Kovalenko. All I did was to take a minute or two to look up the date in his book Fountain Pen Patents 2. A wonderful resource.
