This set arrived yesterday. I will try to get more pictures up this weekend, but I am too excited to not post. Every thing looks right for a first year set. The clip is right. The filler is right. The imprint on the blind cap is super sharp and indicates first quarter of 1941. The gold content on the caps is at the top, as it should be for a first year pen. There is a little blue ink on the nib/feed, so it was at least dipped, but it all looks mint. Even the box is quite clean and appears appropriate to the set.
I know it is hard to tell from the seller's photos, but everything about this pen looks right.
I couldn't be happier!
As I said, I will try to get pictures up this weekend, but had to share my excitement!
