you could look at hlloydcycles.com for the transfers. This is not a high end bike, but it may be older than you would originally think, based on a few details. If you remove the rivets then you should source some replacements (a good LBS will have badge rivets). The paint may come up - try a little paint polish somewhere inconspicuous. If not, well, it has aged well. It is a prime candidate for fixiefication.

If you want a better guess at age, we need to see the crank area in greater detail (include a pic of the pedals), the top of the fork, hubs, and where the rear wheel attaches to the bike.
