Poly choke era
I seem to recall that polychokes were popular in the 50s and 60s. Gradually, advertising by polychoke began to taper off and I forgot the last time I saw an ad in any gunzine. In fact, even the used gun racks in my local gunshops are pretty much devoid of any scatterguns sporting polychokes. My son has screw-in choke tubes on his pump gun and I prefer the clean look it offers.
