I won a Lamy factory tour sponsored by a local newspaper, for this coming Friday morning. I live about a 15 minute drive away. I was there once, but the man in charge of drop in with out an appointment visitors was not there and I never made it back. I assume we want to know the nib width slop/tolerance sizes. Like Ron Z did for Sheaffer nibs. What else? Why Violet ink is not in bottles....do many of you use that nice ink? Would you buy a bottle? If you own a Artus pen and have questions, Lamy made them...at least after the war. So I'll bundle up the questions on Thursday, and print them out, and give them to the guide. US Wednesday night deadline = Thursday by me.
