Nose cone Badge replacement/restoration

Hi everyone not sure if anyone can help please?

After a short run this afternoon I returned to find that most of the paint/enamel has come off the nose cone badge. 

After a quick search it looks like these are hard to come by. 

Does anyone know please where I can get a replacement nose cone badge, the car is a 2000 k-series so has the Caterham yellow/green 16 valve badge. 

If not has anyone had these restored/repainted and if so have you got any details of companies used please?

Thank you in advance 

Chris
