Hi, this will be mt first post here prompted by my dear uncle who wants me to share in his interest as a way to keep in touch. Every once in a while he gifts me a pen pen with the understanding that it will be sold on eBay. The only stipulation is that I study the history of the pen in order to present an intelligent and honest post. We've sold about a dozen pens from his collection so far. The reason I've joined today is because he gave me a Waterman Ideal wave brass pendant fountain pen that I can't find enough info on to complete my post. I don't need a valuation - the bidders provide that. I just need the most basic info like when it was made, and some bare bones historical context. I thank anyone here in advance for their time and consideration.
