It would be hard for someone to actually get hurt by it, but I understand the concern.
The actual gauge could burst, but I have had that happen with a brand new pressure gauge in the last 5 years. No one should be looking at a pressure gauge when opening the cylinder.
This gauge reads 3000 psi. I would hope no one would try to use it on a higher pressure cylinder. Do we need to put warnings...
The yoke would be the more concerning item to most divers, but a yoke like this do not tend to fail in a catastrophic and dramatic way. The typical yoke failure is a slight flexing and the O-ring extruding and blowing. It is very disturbing to a beginner and give yokes a bad reputation, but it is really not normally dangerous... at least not physically.
I have seen many vintage undersized yokes flex just enough to be a bit of a concern, but I have never seen one fracture in a catastrophic failure. The worst outcome that I have seen (and can expect) is a blown O-ring that relieves the pressure. Not a great experience, but we get over it.
If you want to use it for display. By all means, just remove the seat from the bleed valve or loosen up the gauge so that it leaks.
