Good evening,
what needs to be adjusted to ensure the correct spacing between the various keys? And how do you adjust the vertical inclinations so that they are all perfectly straight?
(I am not talking about the key dip and leveling)
Thank you very much!

Logically, I would think that one needs to act on the pins. But I could be wrong and talking nonsense. Let's wait for Maestro Ferrarelli.
The weights should also be positioned on the opposite side of the inclination, but those are things the Manufacturer takes care of...

Have the pins been changed? It is a conceptually easy operation, but as we know, on the piano everything is done more minutely. The pins are the "rails" on which the keys move. Are the cashmere felts worn out? I would think that a loose key tends to accentuate the tendency toward lateral tilting. M° Ferrarelli, am I off track?
Andrea1301, I DO NOT KNOW HOW TO ANSWER YOU. Mine are observations because I have much to learn about the piano, but I believe I must "force" my brain to imagine the solution and then be proven wrong or not - and eventually enlightened - by the expert voice.

Key spacing, unless caused by superficial and/or incorrect compression of the cashmere gaskets of the keyboard's front mortises, is achieved by tilting the front oval pins of the keyboard with the appropriate tool, taking care not to damage them! Sometimes this loss of spacing can depend on the deformation of the entire key. In that case, with great care, one can slightly dampen the wood of the key and heat it with subsequent pressure to be able to realign it. However, this latter intervention should only be done in rare cases and with great caution.

Thank you for the answers, I had also thought about acting on the pins, but it seemed like a bit of a drastic operation to me. I am replacing the felts/gaskets little by little; the problem occurs both before and after changing them. As far as the inclination is concerned, the keys are not plumb (the maker is G. Schwechten, the piano is from the late 1800s) and they still have old and worn leather center felts. Besides this, is it a valid method to act on the center pins to adjust the key inclination? (I was told this by others, but it doesn't seem to me that it could work and, above all, it would misalign the entire key in addition to tilting it).

I forgot, furthermore it must be said that it has some ivory plates that seem to have worn down and accentuate the gaps

If it is an antique piano, too many elements contribute to creating discontinuities in the spaces
