OK, no help from the camera body for you here. I looked up the lens, it is about 45 years old, pre-AI vintage without any intelligence built-in.
You will not get a focus confirmation assist in the viewfinder of your D3300. You will not get accurate exposure metering in the viewfinder. You can adjust focus by how clear it looks to your eye, just be sure the diopter adjuster of the viewfinder is set right. It is possible to guess exposure settings on a scene, but it takes years of experience to develop that skill. That is why handheld light meters exist though.
Now a SLR from that time would have a split-ring focusing screen to assist focus on the center of the viewfinder at least. And the light meter in camera body would at least recommend more or less exposure. But your D3300 was built with using modern autofocus lenses as an assumed thing. You can do it, but you are really doing it the hard way.
Thank you so much Hammer.
After your initial reply I tried to match to aperture indicator on the lens to mounting indicator on camera body. Yes the lens sat well immediately but, when I tried to rotate it into the mount to fix the lens, it just wont rotate more than half the distance. Even at that point the aperture ring would stop moving.
I felt applying any more pressure would damage the body so stopped trying further and did some more research.
Yes, as you pointed out, it is pre AI lens.
Then I found the below sheet on nikonians portol which confirmed I should not mount pre AI lens on my d3300.

This sheet is actually quite helpful.
Thank you again for all the findings.
