BluSdUp the aviation one has a bubble of some sort and works without a horizon. Having said that, could not find one in working condition anywhere. Not that I really need it, just for fun.

This bloke says he has a few ready to go. $800 US.
You might need the tripod he is offering too, no idea if they can be hand held. I once saw one in use in a darkened aircraft interior and it appeared to be mounted in the dome.
Search for bubble sextants.
There are loads of cheap ones but the sellers probably have no way to figure out if they are working.
