SOLVED Identification required

This has flowered for the first time ever but I don't know its name. Can someone help identify it please.

 

I've got a few of these,it looks similar, but my mind has gone blank

 

I'm with Pete, my minds blank at the moment. If pushed I would say a Gasteria, no idea on species though.

 

Gasteria of some kind yes that's it Nigel.

 

Thank you @pete and @NigelJ I was thinking Gasteria too but I don't know which species.

 

Looks like Gasteria armstrongii to me

 

Thank you @Sirius I looked it up and believe you are right, I shall put a label with it now
