Hi all, I have one little Esterbrook pen and to me it looks like multiple pens. Can someone kindly tell me what I have purchased? It was purchased from a dealer, not on ebay. What is it? How old is it? Best nib? My concern is that the jewel caps seem wrong for the pen and match the grip. I knew the grip didn't match the barrel when i purchased, but thought it was okay because the jewels matched. Did someone just cobble this together? Also... I recently purchased an unopened box of Esterbrook dip nibs, Assortment #11. I cannot find anywhere what the contents are. Is it worth more to leave intact or should I open the box and use some and sell/trade the others?? Seems to be the latest version of box. Thanks all for ANY help!!
