Fly sheet for MSR Hubba Hubba (2 person tent) (Hove Green BN3)

Hello, it’s a bit of a long shot but I have a much loved MSR Hubba Hubba tent but the fly sheet has lost its shape over time so can no longer be used. MSR don’t sell replacements as the tent is too old, but the fly sheet for the Hubba Hubba NX or the Hubba Hubba 2 would fit my tent. Does anyone happen to have a spare one? I would much rather rescue this tent than buy a brand new one if possible… any help would be much appreciated! Thanks!!
