Yes, as noted last year I returned three of Waterman Preface model pens to use to allow me to clear the logjam of colourful Noodler's inks at the top of my ink table. I enjoyed those three pens so much I reactived the other nine as well.
There is not much more that I can say other than I like an enamelled pen in red.
A medium nib, writes well.
As I mentioned in my last post the change in algorithm has brought to the top a few lessor (in terms of quantity of their ink that I own) ink manufacturers. Diamine is not one of those, being second on the list behind Noodler's. Its been a while since I have had many Diamines in rotation - they are general great inks with super boring bottles.
Damson entered my collection in May 2011 and was last in my rotation in July 2014 - so it has been a while. It is a very nice dusty violet colour that reminds me a lot of R&K Scabiosa. There is no shading or sheen to be seen from this medium nib and if anything I would say this ink is on the dry side. I use Tomoe River paper so a dry ink is not necessarily a negative.
