Anyone know how to date the cases that came with high powers over the years?

Brass zips,   "Browning" logo locations, w/wo interior pouch  etc

thanks

Copied from the old FN HiPower forum regarding the pouches. I cannot vouch for its accuracy.

T series thru 70s: Gold zipper, logo on flat side, elastic pocket inside pouch

70s thru early 80s: Gold zipper, logo on spine non-elastic pocket inside pouch.

Early 80's to ??: black zipper, deerhead logo on spine.

Renaissance model came in the shearling lined pouch.

Copied from a 2007 post on 1911forum.com:

They were still giving out the pouch in 1981.
From what I can gather, there were at least 3 different pouch configurations:

1. Red liner, BrowninG on the side with elastic muzzle pocket and brass zipper (1960's ?).
2. Red liner, BrowninG on the spine with cloth muzzle pocket and brass zipper (1970's ?).
3. Red liner, BrowninG on the spine without muzzle pocket and plastic zipper (1981).

Hope that helps you out some.

thanks!
