Vintage Hilborn 4hole injection HAT . Barrel valve has 25 which is a 56 according to Don at Hilborn. Linkage includes spring return tang. Lines look decent. No nozzles. Shaft/butterfly’s/linkage are smooth and have no slack etc. It was polished at sometime in its life. Apparently was serviced at Kinslers once- it had at the time of the photos a kinsler service tag glued to it. Is a used unit but still got lots of life left. 662-542-0796 call or text after 330. 1500$. Plus the ride. Thanks for looking.
