If there is interest, I am going to order a bunch in teh next week or so.
I had forgotten that there are several types of Sierra style transmissions.
There is the "Sierra" transmission which is barrel activated and there is the is the style like the "LeRoi" uses which which is finial activated. At this point I'm not sure which style I would be using the most. I guess it would depend on what I'm making at the time.
I'm confused by the terminology. I see the two style of pens as follows:
Sierra - This is the original style and is the same as the Wall Street II. The mechanism works by twisting the barrel in relation to the nib assembly.
Gatsby - The final pen is virtually identical in appearance to the Sierra, but the transmission is located between the clip assembly and the cap. The mechanism is operated by twisting the cap in relation to the barrel.
The tap that I sell is known to match the threads on the Sierra transmission. I have not checked it against the Gatsby transmission. Has anyone verified the size of the threads that the Gatsby uses?
