It is in flower now. I seek for ID again:
Gasteria
Re: Gasteria
The leaf formation and flowers makes me think G. brachyphylla, except that your plant has fewer white spots.

That spots are water marks (probably along with some dust trace).
Re: Gasteria
I would agree that brachyphylla is a good likelihood. I am not sure there is a more promiscuous genus than Gasteria, however, so you may never be sure if it is really the species or a hybrid. But sure looks good for brachyphylla.
