Is this a 100% genuine HMV/ DGAG horn gramophone?

[nostalgia]

This DGAG horn gramophone is up for sale, and I thought it could have some interest to at least have a look at it here on the forum. It is always something to learn from sharing photos.
Are the horn and elbow + back bracket genuine DGAG parts as you see it?
I already have a DGAG horn model, but this model here is slightly different, also with black back brackets, and I am myself not able to confirm if the metal parts are genuine to the machine.
Someone also exchanged the emblem with a US coin, but that is of course easy to repair.
I do not have access to more photos than the ones uploaded. The soundbox is also not pictured well, but it looks like an early Exhibition type to me.

Some original parts are missing like the knurled screw locking the elbow clamp down and the elbow to horn lock screw. The rest looks okay but the elbow might be repro. You can't tell from the pictures really. The horn has been nicely repainted but although possibly correct for French and Spanish HMVs I'm not sure about DGAG?

Needless to say none of the black painted areas should be black. They should be nickel plated. Elbow too.

Maybe 50% genuine (as in "original")?

Horn repainted and not DGAG
Bracket and tonearm painted black - so there may be something terrible underneath
Same goes for horn elbow
Wrong brake
Celluloid plaque replaced by coin - as you say, very small issue?
Horn Y knob replaced with a screw

Thank you, your words confirmed some of my own suspicions, and also added more flaws to my own list. I have seen a black bracket on an original early HMV, but never with a black tonearm, and also the bracket never was all black without gold painting, so yes..this black coloring is obviously not original to the machine.
