What does a SAAPE SP-323 oil blockoff fit??

I thought it was early hemi when i bought it, but it isnt, anyone know??

 

Up!!!

 

Picture?

 

No camera!

 

Come'on somebody has to know!

 

My first thought is it's from Trans-dapt, since their mascot was Super Saape.

 

Don't know if you ever got your answer or not? But Trans-Dapt SP-323-B fits Buick 1953-1960 I know it fits the nailheads but not sure what else?
