WD6 injector pump fill plug?

Just acquired a WD6 and noticed that where I see most pumps have a filler neck with a little flip cap mine has a threaded hole that's had the fitting missing for who knows how long. The question is is there supposed to be a vented plug, a solid pipe plug or does that filler neck I see normally thread into there? By the way I believe it to be one of the earlier style pumps because there is no pressure gauge, no IH or A on the cover either maybe someone can point me in the right direction :D
 
it might be the bosh pump, as the early international's used this pump.
on the international pumps the filler tube is bolted on and has a spring loaded flip oil fill cap.. picture be the answer.
 
If a early IH pump with fill toward rear with hole or pipe in a cover retained by two bolts? It used a non vented screw on cap. Cover and pipe with threads made together for cap if I remember correct.
 
Looked at some old info in case I was mistaken. Some pictures show a cap with threads and gasket screwing into 2 bolt plate. Other pictures show threads on short pipe from plate and a cap with gasket that screws on threads.
 
After more checking looks like a pump number serial break. First was a one piece plate with cap like I remembered. Next a cap that threaded into plate.
 
Does your pump look like this?

I'm pretty sure it's the early IH pump the tag has 65306D1
