i can post pics monday or try and ask the guy who sold me them if he has any i dont think they are really early because they arnet as boxy as the ones they have in repro now. they look like slightly squarer versions of the modern arms. they from memory they have a small usa 175 stamped on back of the driver side......

Check in here for some fairly well researched profile generations.
My guess is late 80 to early 90s.
