First a few size comparisons. From left to right: Edson, M800, Maxima, aero "51," vac "51," 75:

Top to bottom: M800, Maxima, Polished Raw Ebonite Densho, Optima



The pen is a nice girth for my hand, slightly less than the M800. It feels well-balanced unposted, a bit top-heavy posted. It is lighter than the M800, but substantial enough to feel solid.
Nib size is comparable to these others, from left to right Optima, Dani Densho, Maxima, M800:

Pardon the ink on the nib here (it's not rust


My writing sample doesn't do the least bit of justice to this nib. It is really springier than nearly all of my modern pens, and can produce much greater line variation than is evident in my handwriting. Definitely one of my favorite nibs ever. There is a ton of iridium on this broad nib. Here are a couple more shots - I didn't take these two, they were provided by the individual who sold me the pen:


Couple pics of cap and jewel:

The cap take 1.25 turns to unscrew.

You can just make out the imprint on mine:

I really like the understated look of the solid color and clean lines.



I forgot to take pics of the aerometric filling system on this pen, but many if not most of you are familiar with this system from the aerometric "51"s. The pliglass sac takes up the majority of the inside space in the pen, so the pen holds quite a bit of ink. I was surprised to see that the pliglass is totally clear on my well-used Maxima.
Overall, I think this pen is going to knock the blue M605 out of my pocket for a while, taking it's place next to to my trusty Parker 75.
I'm surprised this isn't a more discussed/sought after pen. I simply posted on the Green Board that I was looking for one, and I got 2-3 offers ranging $100 - $150 in price. I've definitely seen them go for even lower on Ebay, as is I suppose the case for all pens.
At any rate, I encourage those of you who were thinking about this pen to go for it. It is a great value and has surpassed my high expectations.
