I bought a Model J pen recently and it is in transit from the seller. I've attached a photo from the seller.
I've just noticed that the cap has the ribbed jewel with no Esterbrook stamp on the clip, which (to my understanding) is an early "transitional-era" cap (1943-1948). The barrel also has a jewel, which comes from the final version of the Model J (1948 and onward). What I've gleaned from Richard Binder's website is that the ribbed cap jewel was gone and replaced by the smooth jewel even before Esterbrook started adding jewels to the barrel end. So my initial thought is that this is a mismatch of two Model J eras.
To those more informed than I on this matter, is this a mismatch? Or is this pairing documented somewhere?
Thanks in advance for your information!
