Interesting Naval Jumper with GREY wool collar and cuffs

[ATJcostumer]

Hello,

Presenting for opinions this seemingly original Naval Jumper that is definitely old and has a seemingly original grey wool collar and cuffs.  To me, this doesn't seem laundry bleached or sun bleached but I cannot find any reference to USN jumpers with Grey extremities anywhere.  The yoke, sleeve placement and pleated sleeves are interesting too ... 

I'd be happy to hear some opinions on the subject.
