Hello fine folk of the forum! I found this at the flea market, it apears to be a vest pocket duofold, it is only slightly longer than my kaweco sport but I haven´t been able to find pictures of this pattern anywhere. I have seen some jack-knife models with these gold waves but this one has breather holes, an inner cap and the christmas tree feed. It came with a "Warranted 14k USA" nib which seems to be too small for the pen thouh it fits the feed nicely. The green section and brown tail cap would sugest they aren´t from the original pen buit they fit perfectly. Have you seen these before? Any
