Johnny there is a guy hangs out on the IAP from time to time from Istanbul a place I am familiar with who has countless tons of this stuff. I say familiar our third daughter has a house on the Asian side of the Bosphorous in Istanbul across from the Blue Mosque just came back from a quick visit there then back to Utah. They are preparing to retire in a few yrs.
Easy access for you to get the timber though my stuff has small voids but is beautiful.
Your pen is exquisite mate lovely shades of colour and texture. Overall Johnny a beaut pen.
Peter.
