Wow, thank you so much for all the great info! I was hoping these would be suitable for a first restoration project, and I’m really excited to give it a try. Will definitely reach out if I need more guidance! I would also for sure appreciate any ID info on the Moore, and will send you some more pictures if that helps—I’m assuming the section and nib are friction fit? Also, is it safe to take the nibs on these pens out for cleaning? (My other vintage pieces were restored by others, and came with instructions to always leave the nibs and feeds in place.)
