I purchased this pen off of eBay and when I say the original listing I believed the photos to be edited until I had the pen in my hands and saw it clearly. Then I thought there was something wrong with my eyes. This appears to be a perfectly ordinary Waterman RED #7 in jet black celluloid with nickel trim, except the nib has a silver tone to it. I've never seen a Waterman nib with anything other than a gold tone. I showed it to some very high profile collector friends of mine, and they have never seen a Waterman nib like this either. One had some theories about it being a depression era pen that may have been made of a different metal than gold, which made some sense, but it's strange to me that I've never come across one before. Has anyone else ever come across a pen like this? Is this some kind of standard model? Maybe someone plated it after the fact? I'm tempted to start polishing it to see if there's a base metal underneath, but not before I find some kind of information. The only thing I'm pretty sure of is that it's a nonreactive metal. I live in Florida and all reactive metals and finishes show some kind of patina relatively quickly. After removing the nib I couldn't find any kind of precious metal hallmarks, although I do have other keyhole nibs missing hallmarks so that may not indicate much.
I've included a comparison "BROWN" keyhole nib in one of the pictures so that it's easier to see the color difference. It's extremely weird to look at and my eyes keep telling me the photo has something wrong with it.
