Usually, it's just a sequential number.  -18 would be the eighteenth 
custom model they did.

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.

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.
