Re:
Great to see another Sun Snipe on the road. I have a Snipe from 1972 which I bought new in 1972. I think that you have seen a photo of it on another thread. The frame of mine is virtually identical to yours, but does not have the oil point on the bottom bracket. The Huret Svelto you fitted is the same as my original equipment and my bike has 'C' nuts fitted as original equipment, so I wonder whether 'S' nuts existed in 1972.
I would be interested to know where you acquired the new decals for your frame as my frame has suffered a bit from winter salt as it now gets used all year round and may require a repaint at some time.
