I have seen very high touch weights in consoles before, and usually if the flanges are free enough, the most likely place to look is the hammer return spring. Some well meaning technician might have strengthened them up the touch weight....causing wear and then extra friction. Of course, key friction is also a high possibility. But if the weight is consistent, it's probably springs. IMO even 55gms is high for a console.

Repinning hammer flanges would follow next, then wippen flanges. Those things alone can make a dramatic difference.
