Blackhill Posted April 24, 2006 Share Posted April 24, 2006 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 Link to post Share on other sites
