Unknown shrub with pink flowers

I found this shrub in a private garden, unfortunately I couldn't cut a small branch or a flower.
Could you please help me identify it?
Thanks in advance.

 

Looks like Chaenomeles

 

Chaenomeles speciosa?

 

Either that or a Chaenomeles x superba cultivar. I don't think they are easy to distinguish at this time, it's really problematic even when the foliage is fully formed.

 

monitor the size; x superba is smaller, say 5 feet by 5 feet; speciosa can get to 9 1/2 feet.

 

The identification guide in Horticultural Flora of South-Eastern Australia states that C. x superba can get upto 6 1/2 feet, it's not clear to me whether the plant in question exceeds that but I would say you are totally right saying that it's C. speciosa, well, as long as we rule out the possibility of other crosses, which would be logical knowing that those are seldom seen in trade.

 

I think the shrubs are about 160 cm (5 ft 3 in).
