Original box fully signed inner outer sides and with crisp use of the pen and maintenance instruction. This pen offered from my personal collection and the color is so vibrant because over the year during collecting fountainpen the sac removed in order to prevent any chemical reaction to the barrel.
We old times believed back then the rubber sac created a chemical reaction along with the ink if left in the barrel. We advanced pen collectors we practice that and we have taking precautions.I have posted picture the critical point that you need to know about the clip been secured and not loose, the lever that open and closes tight, original feed that aligned properly, the barrel threat that all engaged and turn several full turns. The cap ring is not loose and also the end of the barrel indicating the #94 designation of the model and the cap circles been crisp and nothing cracked or broken. The waterman's logo and lettering is crisp as well.
I did used this pen from time to time on a special occasions and after cleaned thoroughly, the sac removed and stored separately. All my pens stored in good environment and moderate temperatures in their cases. Some also displayed in my study. This waterman's ideal pen ca 1930's is investment opportunity and priced accordingly.
