Your Velo-Sport shop sticker may have a serial number on it that could help date your bike. The photo below is the Velo-Sport sticker from my '74 Raleigh International and has # 02673.
I think having a Velo-Sport shop sticker adds a little class to your bike. It was a significant shop in the development of cycle racing in the USA.
