Hi Guys,

I've come across an old bike with a big box of spares in an old shed. The frame number is simply 830 on both the steering stem and on the frame itself. IT has Nervex lugs and the Olympic logo, same as this pic found online.

Any idea what vintage it may be? I know the nervex lugs werent around until later, however the 3 digit frame numbers have thrown me a bit.

Any expertise would be appreciated. I can get some more pics tomorrow...
