Neil,
A hardy welcome to you. Glad you have joined us. I'm assuming you are in the UK but you have not included location info in your profile. Regarding chrome, there have been many posts here for plater recommendations, really, around the world. If you let the group know your location, you will surely get rapid response as to someone in your area or, at least, to whom it would be reasonable to ship.
I must admit to being envious of your project. I wish I had such a bike in front of me to dig into.
Richard L.
