Not NOS White I'm afraid!
Basically I spotted that my workmate had put some old 2.1 amber sidewall Porcs (pretty certain steel bead) on his bike. They've been used but there is a reasonable amount of tread left. I mentioned to him that before he wears them out that there maybe interest from the retro crew.
As long as he has a pair of reasonable tyres to run then he's quite happy to part with the Porcs. So if your after a pair of retro porcs for a project and have some tyres to swap (or money to buy some new tyres) then let me know.
