to avoid extensive facial reconstruction surgery,
get a Nitto Technomic or Perioscopa stem, they are made with a much longer quill .
or get a TUBE TYPE STEM RAISER It is reduced in diameter to go inside your fork , 22.2/7/8"
then the upper portion has the same Inside diameter to insert your stem into..
the ID on the top is the OD on the bottom..
see:

the tube stem raisers on the bottom.

To replace the stem, I see on pictures that have been sent suggest the bike is a 86 or 89 frame and the stem is a SR Custom Alloy 100 mm. So I can go online and order a 130 mm 22.4 mm or 25.4 mm (opening?) quill, threaded stem? Does that fit this, does anyone think might be correct? I still do not understand how to determine the opening, is it 1" or 1 1/8"?
quill, threaded stem? Yes, you have a threaded steerer-tube with threaded headset that accepts a quill stem
is it 1" or 1 1/8" The outside-diameter of the fork steerer-tube is 1"
130 mm 22.4 mm or 25.4 mm Your existing stem is 100mm extension, do you want a 30mm longer reach to the bars? The diameter of the quill that goes inside the steerer-tube is most likely 22.2mm. The handlebar-diameter that fits into the stem's handlebar-clamp is most likely 25.4mm.
I still do not understand how to determine the opening You want to get a set of calipers. Very helpful for working on bikes and determining the dimensions of various parts:

Thanks to all who gave me suggestions, especially fietsbob & DannoXYZ,
DannoXYZ the diagram/picture clearly shows what I am asking about.
I do not want to extend my reach, I want to have the reach higher from the ground. I like the drop handlebars for the rare times I get down and grab the lower ends, but I am wanting what I think would be more comfortable, say not 30 mm but something more extreme (especially if I am going to go the trouble of raising them), something around 60 - 80 mm (hovering around 3 inches).
And for bicycles and (any other excuse) I now "have" to buy another tool, I'll get a set of calibers to measure stuff with.
Also based on the EMPHATIC responses regarding my currect stem insertion, I did lower it to the recommended line. Having been riding through the summer into the fall, maybe the lowered angle is not as "tight" on my posture as in the beginning of the spring when I was started to commute to work on a more regular basis.
