Thank you Jerry! That's a huge relief that I don't have some farmer's hodgepodge model as it appears. Now we are getting somewhere. Mine is still different from yours in that there is no slot for the selector handle at the top right of access door. What is this in the below pic of my upper part? Any idea? Do I have a type T-178 model #? or am I looking at a type T-179 model # now that it appears I do not have a type T-177?

Thoughts?

I'm interested in Deep Rock and Kerr McGee items especially if they are marked B.A. Tramp Oil
