I have a hot water cartridge in my deck mounted tub faucet that needs replacing (picture attached). I am trying to find a match but am not having any luck. I have looked through the Danco replacement catalog but found nothing. I have taken it to a local pluming supply place and they said it was made by Sign of the Crab. I contacted them and they said it's not theirs. I have seen ones that are close but not 100%. Any help would be appreciated.
