Port kegs, will they do mead?

Picking these babies up soon but I don't have any background info on them, only the photo. Does anyone know about this specific model of keg, and whether i'm safe to put my mead in it?

Failing any definitive answers I'll probably just give 'em a good wash and give it a go, but I'd prefer for months of solid fermentation to not go to waste.

they are just under 2L in size and stainless steel. mine has port in it and I've never used it for mead.

Awesome, thanks barls. Checks a couple of boxes at least. I'm assuming they aren't rated for pressure?
