name the iris please

I planted this iris many years ago just 4 bulbs and moved them into a mixed pot a couple of years ago .  Everyone commented on them this year and I'd really like to plant some more.  Can anyone name it please?

I' ve just bought some of these Irises from The Range store . They are called Angel Wings. I also bought "Symphony" mostly yellow and "Sky Beauty" a lovely pale blue with a touch of yellow. They are lovely large bulbs and I thought a bargain price. hope this helps.

I give it a try thanx lilysilly
