I am from Sydney Australia and am a Parker 75 collector owning some `150 including the LE Spanish Treasure Fleet, RMS QE and the Bicentennial in each of the boxes. Interestingly I acquired the Bicentennial 9000/10000 in the wooden box and then got the pewter box and found the pen also numbered 9000/10000.
Welcome. :) I only have one Parker 75 -- my dad's -- it's a milleraies with an M nib. I love the way it writes and how easy it is to take care of. I'd like to get a cisele some day because that seemed to be his default favorite.
