Thanks everyone, your comments are highly appreciated.
My current thinking is that a rebuild of the wearing parts is needed, and I will consider updating the gears and chainset - especially if these are not original. I'm not concerned about it being equipped with fully authentic parts but I'd like it to be sympathetic to the priginal set up.
The one part I'm not happy about is the badge. I don't think I'll be able to make this look nice, what would be best practice for this?
Thanks again for any advice.
