First, a description of each size and it's exact measurements.
Esterbrook J - This is the largest pen in the J series. This pen is the thickest and longest of all three. It measures 5" when capped.
Esterbrook LJ- This is second down in size from the J. It's as long as the J measuring 5" but it's thinner than the J model.
Esterbrook SJ - This is the "baby" of the J family. It's thin like the LJ but it's also shorter than the J and LJ. It measures 4 3/4" when capped.
So, now comes the hard part: determining which is which when you have no reference handy. Here's the secrets:
Here are the three sizes compared. Not to hard to tell when they're right next to each other. Left to right: J, LJ, SJ.
Just an FYI: Red J, Copper LJ, and another Red SJ.
Here are the pens uncapped. The LJ and SJ caps are almost identical.
Alright, time for trick #1. The jewels. This only applies to the J pen. If you look closely at the Red J (on the left) you'll notice that the cap jewel is bigger than the barrel jewel.
How about an up-close shot. There's a substantial difference here. This is one easy way to tell if you have a J on your hands. This method never fails.
Now for the real giveaway secret: The levers.
Here is a J lever. The lever is almost the exact same size as the distance from the end of the lever to the jewel.
Here's an LJ lever. Same thing as the J, the length of the end of the lever to the jewel is the same as the length of the lever.
Now here is the SJ. The lever length is longer than the distance between the lever-end and the jewel.
So here's the keys to remember. Do these in order and by the end you'll know exactly what model you have.
- First, check the jewels. If the top jewel is bigger than the barrel jewel, it's a J.
- If the jewels are the same size then you've already cut out one option. So now you must find out if its an LJ or SJ. The easiest way to do this is check the lever to lever-jewel ratio (as I call it).
That's it! With these "techniques" you should be able to determine the model of almost every Esterbrook you come across.
Hope this helps!
