I just wanted to share some pictures of this handmade Guider nib that I have been using for a pretty long time now ( since 2008 or so). I recently purchased this plain brown "medium" sized pen and transplanted the nib into this. I think the plain brown colored pen with the golden accents is a worthy match to it. http://i264.photobucket.com/albums/ii197/hari317/Guider%20Acrylic%2014C/Medium%20Brown%2014Ct/IMG_1044.jpg http://i264.photobucket.com/albums/ii197/hari317/Guider%20Acrylic%2014C/Medium%20Brown%2014Ct/IMG_1045.jpg http://i264.photobucket.com/albums/ii197/hari317/Guider%20Acrylic%2014C/Medium%20Brown%2014Ct/IMG_1047.jpg http://i264.photobucket.com/albums/ii197/hari317/Guider%20Acrylic%2014C/Medium%20Brown%2014Ct/IMG_1046.jpg http://i264.photobucket.com/albums/ii197/hari317/Guider%20Acrylic%2014C/Medium%20Brown%2014Ct/IMG_1048.jpg http://i264.photobucket.com/albums/ii197/hari317/Guider%20Acrylic%2014C/Medium%20Brown%2014Ct/IMG_1049.jpg http://i264.photobucket.com/albums/ii197/hari317/Guider%20Acrylic%2014C/Medium%20Brown%2014Ct/IMG_1050.jpg A slighty oversized 5.2mm feeder had to be installed, fortunately, I found one in my parts box. http://i264.photobucket.com/albums/ii197/hari317/Guider%20Acrylic%2014C/Medium%20Brown%2014Ct/IMG_1051.jpg http://i264.photobucket.com/albums/ii197/hari317/Guider%20Acrylic%2014C/Medium%20Brown%2014Ct/IMG_1052.jpg Cheers!
