Searching for an odd machine oil. Assistance.

Didn't know that, I've learned something new. So just buy sewing machine oil (check the MSDS if uncertain what's in it) or ISO 66 hydraulic fluid.

If I remember right the temperature/viscosity dependency this one should be around your values:

This is the nearest thus far.  Cheers!

Oils like 3-in-1 and other hardware store oils typically contain waxes and other junk that harden and form a varnish on the lubricated surfaces.  This has caused many sewing machines to seize up.  You can search this forum and find posts about it.  Even happens on furnace fan motors that have run for years with no oiling, suddenly seize up a few months after being oiled with 3-in-1 oil.  Quaker State is an example of automotive oils with a high wax content.  My old Ford would start running rough, getting to the point it would barely run.  I had to pour STP gasoline treatment through the carburetor while running at high RPM to loosen up the sticky valve stems and it would run fine for a period of time.  One day my Dad, a professional mechanic, asked what oil I was using.  Told him and he said to switch oil to another brand as QS had lots of wax and that was causing the problem.  Switched to a different brand, lower wax or no wax content and had no further problems. 

Beware of oils that have high wax content or additives that cause a build up of varnish for all your equipment, sewing machines plus ...

Many years ago I thought I knew it all & was working on a neighbors treadle machine & the more oil I gave it the tighter it got until it wouldn't turn,I took the head out of the cabinet took it to work the next day & told the seasoned mechanic what happened & he broke out in laughter.After what seemed like 5 minutes he told me they've been using 3 in 1 & the new oil caused it to jam from the wax.There were some parts on the machine(underneath) that even had some waxing icicles almost 1/4" hanging off of it.So he told me to take some kerosene & re-oil the main bearings & it should free up,that did the trick & sure made my neighbor happy when I took it back.

The closest from the top of my head would be a hydraulic oil like Castrol AWH32 or something similar with a viscosity of 32 cSt. But I know it isn't exactly what you asked for. 
Another alternative is synthetic lubricant for refrigeration compressors. 

Hanseline produces a fine sewing machine oil, it is made in Germany, and you can get it in 0.2 or 1L bottles (I don't know how much your machine needs).
I have used it for my sewing machines and been very satisfied with the performance. Nadel24.de sells it for 2.98 Euro for a bottle of 0.2 L, I normally buy a bottle or two whenever I stock up on needles for the sewing machines.

He needs to just buy a bottle of 10 spindle oil.  It's cheap and readily available. $40-50 a gallon.  It's all over the net in pints and qts as well.

Many sewing machines call for common spindle oil and it would work just fine on his Pfaff.

Most Pfaff machines are mostly clones or based on Singers, the same machines everyone else copies and recommends 10w spindle oil on.  It's also widely used on textile machinery in general.
