Which acer?

I got this little acer from a house eviction last November. Turns out it's stunning! No clue what type though! Anyone any clue?

And any hints for care? It seems happy enough in its little pot but I would like to plant it out long term. However so far, it's the first acer I haven't killed and I would like to keep it that way!

 

Hi It looks like orange dream , if planting in the border you will need a sheltered spot out of the wind as this is to blame for most of them failing , also part of the day 12.00 3.00 out of the full sun if you can , if you cant keep well watered.

 

Awesome, thank you I have the ideal spot for it. I'll put it there in the pot for a while and monitor, if it doesn't get any wind burn and the shade is good enough then I'll plant it out properly.
