Roger Martin shared this ad for an original Ford GP Pintle hook, but I haven’t followed prices on these to know if this is a good one or not. (You can get repro versions on eBay for $175)

“I’m looking to sell my ford GP pintle hitch prototype asking 500 located in vermilion Ohio willing to ship”
I don’t know about this one being a prototype. I sold a good original back in 2017 for $200.
I was assuming the seller meant for a prototype jeep rather than it being a prototype? I just don’t know much about the pintles.
