Depending on how old these OCXOs are, I may have an original datasheet

Dave, obviously it would be great if you did have one, but from the data
sheets, Vectron assigned an arbitrary part number suffix to the generic
number once you ordered the options you want, in this case the -18
suffix, and it can't easily be translated back...
Usually, it's just a sequential number. -18 would be the eighteenth
custom model they did.
You would have to look up their database to find the formula.
That *would* be nice (and not just for Vectron)
The challenge is that sometimes the combination of specs/options is
something that reveals information that's a competitive advantage.
There's a limited number of buyers and sellers of these kind of things,
particularly for more specialized applications. For instance, if there
were two companies in a particular niche market, say that used something
like 31.415926535 MHz, and you saw that Vectron was making that
oscillator with a particular combination of temperature range and
stability requirements.. and you were bidding on an RFP which oddly
enough had exactly the same requirements.
Would be nice if they would publish that list for acient devices with
datasheets, as service to time-nuts, but it's dreams. But what else can
a time-nut ask for after the H-maser and more measurement toys for
Christmas?
PS. Santa, you can fit the H-maser under the Christmas tree next to my car.
I just ask for gold bars. I figure I can turn those nice compact bars
into whatever I need, and that leaves room for other stuff, and makes it
easier to water the tree.
