Info Needed Mazzilli '86 Mets Bench Jacket

[Swoboda4]

Looking for info on this '86 Mazzilli game used bench jacket. The anniversary patch is not original, looks to have been placed over a small remaining small piece of the original patch that was removed for some reason. The removal of the original was mess that left small holes in the jacket sleeve. Has anyone any info on this jacket? Were anniversary patches taken off '86 jackets for re-use in '87? Does anyone have another '86 bench jacket that they can show an image of the front and inside sewing pattern of the anniversary patch? Thanks
