Help dating this beautiful Windsmoor coat. 1950s? Thank you!

Hi Team,
I'm from Australia and was shopping at my local OP shop and found this amazing coat. It's a cream Alpaca (Lama) wool coat knee length. I've attached some photos the tags have that 1950s /1960s look and are hand sewn in. The garment was handmade in London. I'm terrible with the shape and can't match it with a decade. But would love this community to bits if some one had more of an idea about what period it came from! A big thank you I'm advanced.

 

Here's one more snap!
