Yeah, it's kind of unique. Basically a Raleigh Sprite 5 speed with Humber branding. Serial number seems to indicate a 1972 date. I had an alloy GB stem and Nitto track bars on it, but have since gone back to the original shorter steel stem and inverted the North Road bars. Kept it a 5 speed but with a 14-32 Suntour freewheel and Cyclone derailleur. Also went with alloy 700c wheels. I'll try to throw a pic up before it gets dark.

When lining the lugs with the pen I kept leaving a perpendicular line whenever I lifted it. They cleaned up easily with a fingernail, though. The pen itself was fantastic. I kind of have a peeve about too thick lug lining, and I am happy about the flow and thickness of the lines these pens put down. I am toying with the idea of box lining on this bike. The three pack of pens came with gold, white, and black.
