North and Judd owned W-C for decades and had moved their production (at least their toilet production) to Nicaragua and stopped paying any attention to it. Tooling and other things important to the production of bronze components became seriously worn out, resulting in toilets that leaked and other problems, but that was in the '90s. N&D sold W-C to a couple of investors who moved production back to the US with all new equipment and made top quality toilets again. But unfortunately they ran out of money and had to sell it...I don't know who bought it, but never heard they moved production to Mexico...Thetford bought it from them...I don't remember what year, but it's entirely possible that it was Thetford who tried making W-C toilets in Mexico before they folded W-C altogether.
