A handsome array of Tortoises! You have the added weight in your Onoto, as well, don't you? I think it is a very nice addition. My one modern Conway Stewart, Churchill in Amber is more transparent that I imagined when ordering it & the "innards" being visible have always bothered me. Unless I hear from anyone with a different view, I have asked for the inner liner for the Onoto in Tortoiseshell.
I really do like the White Pelikan better than the Brown, my white seems to show the Tortoise better & I was surprised I would like it as much as I do. The size difference worried me, since I had only the 800 & had never seen the 600, until receipt; Once uncapped & in use I never notice it's smaller size.
Thank you for sharing these pens. I am sure they have provided much pleasure. I also enjoyed seeing my Parker Premier, resting along it's larger family. It is another pen that I forget it's size, when using, forgetting it is a 1980's pen.
