Hi Everyone, I just got this lovely Kelly 28 sellier in graphite box from 1987

(second picture with my gold b35 in gulliver, also vintage from 1997

). She was likely improperly stored by one of her previous owners and developed a crease in the front. First few pics were when I just unboxed her. Last pic was after I massaged her to help regain some structure back. My after sales specialist recommended a pillow which I have purchased when she returns from spa.
She’s currently en route to Paris. He is inquiring about making a strap for me and adding the double rings, in addition to cleaning/conditioning and minor glazing repair, etc.
I asked him if the spa can clean and polish the hardware but he suggested replacing completely with new hardware. I don’t mind the scratches/patina (no black/tarnish/chipping other than on the pins), but the lock and key are badly tarnished. He recommended replacing all so they match. I am somewhat torn about replacing the hardware when it’s not in terrible condition. Any thoughts? TIA!
