1969 ABS-spec Wilson Bulletback irons for sale

I have a set of 1969 ABS-spec Wilson Bulletback irons (2-PW plus Gap and SW) I am interested in selling. I purchased them on line from someone who purchased them from John. Based on timing and appearance this link may be the original listing, but can’t confirm: Complete ABS Spec Wilson Set with 69 Bullet Back Irons. After purchase, I sent them to John for a tune-up and to be sure they were still at ABS-spec. Selling them since I think someone on this sight would put them to more (and better) use. They are essentially in the same condition as when I purchased them. I have $550 into them ($450 purchase price + $100 for John’s tune up). I would like to break-even. Happy to post photos if anyone has interest.
