Still have the manual?
If so, it may have a parts list and maybe order from the manufacture...

Hmm. My owner's manual for my little Sanborn has a parts list. My owner's manual for my Industrial Air has a parts list. I would venture a guess that yours would also. As to you believing the compressor is dying, the part of your description that is throwing me is the statement that it is slowing down. I'd pull the belt(s), disconnect the discharge tubing and try rolling the compressor over by hand.
can't read the model #, is it 216 v ?

116VL, just like the decal.
I thought it said 1167L ... I believe you are correct .
Ha ! Too Funny ! All these years I assumed it was a reference to the voltage and it was odd that it was 116 volts but never gave it much thought .

Single stage it might not pay to rebuild it compared to a buying new pump

I know I'm right....
pull the piston and just mic the OD and the ring thickness. Probably standard sized ring. The reed valve/plate may also be dirty. The eccentric bearing could be a sealed unit (rod bearing) cylinder could be floating. Depending on how cheap it really is, although it looks like a cast iron jug.
Mine was going VERY slow on startup. It would trip the breaker 8 outta 10 times. Turns out check valve inside was allowing air past, so theoretically was under psi to start. The hard starting eventually took out the "start" capacitor.
Approx $35 later for capacitor and valve, good to go!
Is my compressor shot?

I believe that company is still in business.
Just out of curiosity, what's the CFM rating? I can't read it.
Is that a single stage pump?
I have a model 338 that's been converted to 240 (from 3 phase).
It's been a damn good compressor, despite it's previous life in a body shop.
If it went South, I'd not think twice about rebuilding it.

I had a Compair/Kellog that I had to replace because I couldn’t find parts for it anywhere. Turns out it was a 2 year only model.
I always thought it was a single stage .
The cylinders look equal in size.
I drained the tank (of air) and started it again . It runs fine until the pressure starts to build to around 80 psi then it starts to slow up . It did not knock though ...which leads me to think Steve is on the right track and the valve is stocking .
That would be great if I dont have to do a rebuild.

Ah, your situation is clearer. Now it sounds like a motor problem. It looks like you have a capacitor start/capacitor run motor. I'd bet the run capacitor is going south on you.
I found a thread on another forum that referenced this company.
Factory Air Compressor Parts
They also said two different compressors were used- one has parts available, the other does not.
Your main body looks like mine, but with different cylinders (mine are 2 different sizes), so I hope ours are the ones with available parts.

could adapt this $139 HF pump to your nice tank. Probably a Chinese close with the same parts.
Here is the breakdown pdf https://manuals.harborfreight.com/manuals/67000-67999/67697.pdf

Hmmm .. that is interesting . How do I address that ?
Could be the electric motor.

Read through this first. It should answer most of your questions.
What is a Capacitor Start Capacitor Run Motor? - its Phasor Diagram & Characteristics - Circuit Globe
This is interesting reading also.

My personal experience (on a limited number of motors) is that when the run capacitor fails (or is failing), the motor won't deliver full power, draws more current, and gets hotter than normal.
