DP是墨水笔量产商,最初制造滴管笔,最终改为生产压杆自灌墨墨水笔。DP过去生产中低档品质的滴管笔,他们早期的滴管比质量非常低,可能是他们只是买入这些笔、然后打上自己的商标。后期的滴管笔质量有所改善,他们的滴管笔包括嵌贝母的、包金[注1]和镀银的产品。DP也销售橡胶墨囊灌墨的笔。在20世纪20年代改为生产压杆自灌墨墨水笔之后,他们的产品品质确实有所提高,并且制造了一批非常不错的平顶钢笔——看起来非常想National Pen Products的产品线。他们销售全线的男女用笔,甚至长短笔(没看懂)。在20世纪20年代,某些情况下其笔的商标是“新DP”。他们的产品线在30年代开始下滑,貌似他们的笔又从其他制笔商那里买来、打上Diamond PP的商标。20世纪30年代,他们似乎聚焦销售桌面产品,他们的商标包括Blofil、Protector、Diamond Point and Selfill.
Ever Rite fountain pen that was made in New Jersey in the 1930s. It is a long short style pen. When the cap is screwed down, the pen is very short, but when you post the cap, you have a long pen. I guess it is an eyedropper fill pen, there is no filling system but the section does have a long neck on it? No nib.
