The Airmail 69T /Reg D is an Indian fountain pen that I purchased from Kevin at FountainPenRevolution.com It costs $16 plus shipping. I call it the Reg D due to the markings on the pen, but Kevin lists is as the 69T. For this review and currently for writing I've got the pen filled with Chelpark Royal Blue, a very nice regularly colored blue ink.
This is a good looking fountain pen. Of all the Indian eyedropper pens I've ordered this is the best looking. The blue swirled acrylic is shiny and bright the surface is perfectly smooth. The clear acrylic portion of the pen is also perfectly smooth and crystal clear. The clear acrylic has the thickest wall of all the pens I've ordered from FPR and would not crack easily. It's very sturdy feeling. The pen is thick, but not too thick just enough to encourage a loose relaxed grip which is fantastic for long periods of writing. The section is made of the same swirled blue acrylic as the cap.*
The trim is all silver colored while the fine pointed steel nib is gold colored. I always find this odd. The nib arrived quite scratchy. I used the macro lens on my iPoo touch to find out that the tip was not aligned, the left side was higher than the right. I was easily able to adjust this down. I then ran it over a nail buffer to smooth it out. I further adjustted the nib to write a wet line, rather than the somewhat dry line it was writing. Writing and sketching with this pen is now pure joy. In it's scratchy state it was okay, adjusting the nib would have sufficed, but the added smoothing of the nib just made it better.
It is an eyedropper pen. For sealing it all that is needed is a small amount of silicone grease, I went ahead and added a small o-ring. Before tuning the pen I noticed some blobbing but I suspect that won't be the case now that I've adjusted the pen. The pen holds around 3ml of ink, which is pretty standard as far as eyedropper pens are concerned. It's also a pretty lengthy amount of drawing, especially with it's fine nib.
*The pen does have a faint "Noodler's" vegital resin odor to it. It's much fainter than any of my Noodler's pens.
I was not compensated for my review of this pen, I purchased it for review. I am simply a happy consumer.
