I have found very few all-steel Vacheron Constantin 4072 (without any gold on case, bezel or crown). Across those found, we do not see the same dial twice. I have not found many, so I expect we will see duplicates after additional research. While I list all seen below, I would caution that it is extremely likely that some are redials.
Those seen to date, shown in order of case number, below. Differences not listed, such as rings on the outer portion of the dial or within the registers, can be seen in images.
– Tachymeter scale, Base Mile 400; 3 tone silver
– Tachymeter scale, Base Mile 400; silver
– Tachymeter scale, Base 1000; 2 tone silver
– Pulsations scale, 30; 3 tone silver
– Tachymeter scale, Base 1000; matte silver
– Minute track only; matte silver
– Minute track only; 2 tone silver
– Tachymetre (1000) and Telemetre scales (1km); 3 tone silver
– Tachymetre (1000) and Telemetre scales (1km); 2 tone silver

Numerals are only ever seen at 12 and 6, if at all (if not, we see a pair of markers at 12 and one at 6), and are shown as as either Arabic or Roman numerals. Index markers are in nearly all cases baton, sometimes with pointed end.
I am not including an image of the dial from Vacheron Constantin’s Les Collectionneurs (serial 273565, available as of 2020) in the set above as it has been replaced from the dial at Antiquorum in 1989. You can see the piece below:

Registers
Broadly speaking, there are two designs for the registers, one with outer tracks and one without.
Vacheron Constantin 4072 with V295 pieces will have a 45-minute counter, and those using either V434 or V492 will have 30-minute counters.
Designs follow the below pattern, though note outlier below.
Running seconds counter:
– Marks at each second
– Longer marks at the 5s and shorter thicker marks at the 10s
– Numerals on the 10s for the running seconds counter
Minute counter
– Marks at each minute
– Thicker marks on the 5s
– Numerals on the 5s
– On design with no outer tracks:
— Longer marks at either 3, 6, and 9, or, unusually, at only 3 and 6.
Outlier:
One piece has a design with the following differences from what we usually see:
Running seconds counter:
– Longer marks at the 5s, and thicker marks at 15s
– Numerals at the 15s
Minute counter:
– Numerals at 10, 20 and 30 only
A second piece has
Running seconds counter:
– Font/spacing on numerals I would not expect to see
Index marks
The index marks for each hour are paired in color (not necessarily shape) with the main hands. Thus we see:
– Printed black baton index markers with blued steel sword hands
– Printed black baton index markers with syringe hands
– White gold pencil index markers with white gold pencil hands (2 examples)
– Blued steel baton index markers with blued steel leaf hands
– White gold baton index markers with steel pencil hands
– Steel baton index markers with white gold pencil hands
– Gold baton index markers with gold pencil hands
– Pink gold pencil index markers with pink gold pencil hands
