There are loads of places you can have it repaired and refinished but perhaps I'd think about Woodrup in Leeds and ask if Kevin Sayles can cast his eye on it and offer advice.
A guy on Twitter mentioned that it might be stamped on the forks (https://twitter.com/blightyinfurs/statu ... 7555519490) he also put me onto this site.
Thanks for all the help/interest. I will put up pics as it gets rebuild/come back with queries
