USN rain gear before N-2

Just saw a set of USN rain gear on eBay and I bought them instantly,

but it is not N-2 or the one in 1941 navy regulations at all,

seems to the one of the experimental rain gear between 1942-early 1943.

The rain jacket does look like N-2,

but with bottoms at chest.

And the trousers are between the one in 1941 regulation and N-2 rain trousers,

the shape is similar to pre war one,

but with buckles on each side and zipper in front.

honestly I just bought them and the photos are from the seller,

hope I can get them soon to share more photos of them!
