One thing that does leap out is that nasty grub screw on the D string tuner, which probably explains why the E & A have been replaced. It goes like this...
If you tighten the locking nut/ferrule using a spanner & wind it so's it's
tight, it causes the capstan post to bind, so extra effort has to be applied to turn it.
The 'ears' are an interference fit onto a splined shaft & the extra force messes that up so that the ear works loose & falls off.
That's fixable - either a horrorshow repair like the one in the photo, or something a little neater:
I drilled right through the ear & shaft, applied a couple of small countersinks and then used a short nail cut to length & squeezed up in a vice to act as a cold rivet.
The other thing of note in the picture is the bit in the arrow's pointing to. The threaded part of the body has a section ripped out of it - caused by the post binding 'cause the nut was done up too tight. That's
not fixable.
So... I'd recommend slackening all the retaining nuts right off & then wind them on until they're finger tight. Then apply the spanner but only give them a quarter turn or so - just enough to nip them up to stop them from working loose.
At the same time, check that the locking collars are backed off too (those things with the little hole in - they unscrew). They're a nice idea, but not really necessary IMO, plus they're a complete pain to use without the special little spanner
I got lucky on Ebay & found a suitable one IIRC it cost me around GB£20 - haven't seen one since... 5 years
