Hello Christian,
That's a good frame, as most 45s frames still are.
Yes, the reel should be straightened and painted first.
But remember, NO powder coating. Conventional painting is the best.
I can't personally recommend a sharpening service in Melbourne.
I know ADE use Foley grinders at Cheltenham.
Administrator Deejay is the star of the videos.
Hopefully, now that he's back, he will want to say something here.
As to the 3/4 clutch inner half, I'll leave that to member Bonnar Bloke.
Hope this helps.
