HI
Would someone be so kind to help me identify the date of the manufacture of this original L-2B jacket?
Thank you

Guys I should have done a little more homework before posting. I’ve got it down to 1957-1958 for the 7448C contract. It’s an early L-2B contract from Skyline Clothing Corp. If anyone has additional info please post at your convenience.
Thanks

Great jacket, Burt. Skyline made excellent MA-1 and L-2B jackets. I love my own.

Thanks for the comments.
This is a great early period summer weight L-2B jacket but they run rather small for the size. Not sure if I’m going to keep this, as it’s tight fitting, and short in length for a size Extra Large.
