Sympathetic early road/club restoration

Re spraying a frame at Argos would cost around £300+/- for a single colour + lug lining + decals applied. It also depends if they have got to fill some pitting and how much as that will alter price. Then your decals £30 ish. I can highly recommend them but I understand that Mario Vaz is cheaper.
Most chroming places will take bike bits but check first because the most industrial places will prioritize big jobs and might leave you waiting months for your bits. And I found that it will be more expensive if there is a lot of polishing to pitted parts to be done, as this is time consuming, but otherwise will show if rechrome without polishing.

I know but I don't plan to put back decals or lug lining probably going for just the chroming and a black enamel frame and forks like the evans above but without decals, I imagine this bike was a club bike and has simple no frills construction so I'm not to bothered about fancy stuff just the basics done right

I am probably gonna take all the bit's I want done to London Chroming to ask their advice and get a quote, they seemed up for it on the phone
