Here are my favorite pens. Starting on the left you have four R-3s, then a Green R-4, Black R-4, three Blue R-4s and three Red R-4s. Next is a gold brushed R-6 followed by three gold with black stripes R-7s. The next three are Excalibur's, P400, Black and Blue P300 and a brushed chrome Excalibur and a black Excalibur. This brushed aluminum Excalibur, second to the end on the right was bought at Harrod's of London in 1977 while I was on vacation.The last Excalibur on the right is up for debate. It has the same grip as a Pentel Kerry Mechanical Pencil. Next to my black Kerry pencil it is a matched set. Pentel USA told me that the Kerry had no matching pencil but here it is. It is the only one I have seen and is locked away in the basement of the supply room along with the rest of the Pentel rollerballs.
