The tyres were a lucky eBay find - quite by chance I spotted a real old dog of a Mk2 Olympus, but something about the photos caught my eye. I got the images into Photoshop and zoomed in, which revealed that the tyres were original Raleigh Racing amber walls as fitted to the Mk1 Olympus. Amazingly the tyres still had the original paper label wrapped right around the tread, showing they had been fitted to the bike, pumped up and never ridden. The bike was located in the north of the UK which meant another long trip. I got home, removed the tyres and threw the rest of the bike away. It was a wreck anyway and I didn't actually pay much for it.
Obsessive I know but these have canvas rim tape inside them as well.
