Winchester 219 ZIPPER , 5 sealed Factory Boxes

I have 5 Winchester factory sealed "Brown Boxes" containing 25 primed 219 Zipper cases per box.. This is some early Winchester production..

Not sure of what I have, brass/sealed boxes have been hanging around with me for the last 45+ years..

I have also seen .22 HP and .32-40 cases in the 5x5 boxes. Both had WRACo headstamps and were pre WWII.

Yours would probably be from the dawn of the .219 Zipper, around 1938 (?).

Here's a "shoulda" story. In 1985 I was in El Paso and me and a couple of guys went to a flea market down by the railroad. Here's a guy with about 20 boxes of new, primed .219 Zipper brass. Had the money. Shoulda but didn't. Been kicking myself ever since./beagle

Is there any collector interest/value in these 5 boxes of pre-WWll factory sealed boxes of 219 ZIPPER brass?
