As I slowly tick off stuff my surveyor mentioned in his report, I have come to this line item: "The handle on the head intake valve is missing." I have been to a couple hardware stores already to find a replacement handle, but none of them have the physical 1/4-turn limit tabs in the "right" place. Is this one of those specialized marine hardware situations? I do not need to replace the entire thru-hull, just the handle. I also do not want to do the temporary solution of using pliers/vice grips/adjustable wrench. I have attached a couple pictures, in case anyone is familiar with this particular seacock. It's looking more and more like this may be a trip to Fisheries Supply...
