I bought a Schott IS-674 type looking jacket and was wondering if you could give me an age/date range for the jacket?
Almost all the tags are missing, except the "Made in USA" tag which is well worn, but I can make out the size, 44 on it. The inside pocket tag was cut, leaving just a little tail of it left. It has a "Schott" YKK zipper and blank snap covers. It also has quilted sleeve lining - not sure if that is significant for the age. See included pictures below.
