What size pipe for vintage gas range?
I can't find a dataplate on my late 50's Tappan range so I don't know the total BTUs it uses. Is there a "rule of thumb" for sizing black gas pipe for a range? It's a standard 4-burner + oven. I need to locate it a total of 50 feet from the meter. A 100KBTU boiler and a standard (50K?) 40-gal water heater are the only taps now or planned, currently on 3/4" from the meter and within 10 feet from the entry into the basement.

I moved your thread to the plumbing and piping forum.
An older standard stove will require approx. 50 Kbtu

The entire system should be sized for everything to work correctly.
There are many gas-pipe sizing videos on Youtube. Note that a lot of them use 1000 BTU/ cubic foot, and some NG suppliers (like the one that supplies my area) provide 1050 BTU/cu ft gas. You could check with your supplier to get the right number.
FWIW I always run 3/4" to a standard 4 burner stove.

I agree with Steve, I'd use 3/4" to a range.
The last two times I had gas furnaces installed, the installers used 1.25" pipe from the meter to the furnace, reducing for the last few feet. The cost difference in piping isn't much and ensures you have enough volume if additional appliances are added.

I also agree on running 3/4" to range location. Once you have a 3/4" stub out behind the range, you can determine the size of pipe (valve) from that point. For instance a 5/8" x 48" long flex line is good for around 75-106K BTU (to range).
I don't know about MI. Around here the gas company will come out and look at your appliance, look at your stub out, and tell you the specs required for a new valve and flex line. You can't go wrong with a 3/4" supply. It will either supply a 3/4" flex line or it can be reduced to 5/8".

3/4" it is then. I have one tough spot where the joists change direction where I'll need to get creative but that one dogleg doesn't justify the extra expense of CSST.
