That's why these games have GM's. They determine what is available before you can even roll. This is actually one of the first things I told my group: "A successful roll does not equal a successful aim". What do I mean by that? I means that suceeding at a roll does not mean you suceeded in the task you were rolling for.
"You are in a store-room. It is full of old PDF surplus weapons."
"I search for a Lascannon." *rolls* "I got a 3! 4 degrees of success."
"Congratulations you search the room throughoutly, getting a good idea of the inventory. You do not, however, find a Lascannon, as there was no Lascannon to find."
In your example you've rolled for sets of Terminator armour. This would be fine if you were in a place where Terminator armour is likely to be/is being sold. If you're not, passing an Infamy Test shouldn't provide you what you rolled because you were never in a position to get it in the first place.
The views expressed in the above post are my own viewsunless stated otherwise I do not, in any way, shapeform, speak foron the behalf of Fantasy Flight Games.

There are no female Space Marines. Don't believe me?
Gender & Appearance
Due to the special nature of the zygotes that make up a Space Marine's geneseed, all Space Marines are male. - Deathwatch, Core Rulebook, Page 28.
So enough with the Female Marine threads…
