I would say that you would have to email some of them on here that restore that year of trailers and they might be able to tell you or AS could tell for sure. Catch here is was that valve switched out, I do know that AS and other dealers have said that in the 60's the valves and piping was that of a standard household which used different sizes (meaning some used inside diameter, some outside diameter), the new trailers and all made after 1980 used a standard size for all trailers made. This is why the new caps, attachment couplings, do not fit those older trailers. I have this same problem with mine being a 1976 model.
As far as the dump valve thetford has made the majority of the dump valves which are white in color. The other is black in color.
