Fixed choke? Do you need to shoot steel through it? The older Wingmasters are works of art, and arguably the most reliable pump
gun ever made. I had a 1951 20 ga.---sold it and have been kicking myself
ever since. Currently have a couple of older ones and a 1100.
Look REALLY close at that finish. A bead blast and mat blue refinish job is
a common technique to mask a beat up/pitted surface.
Worth $400? As a shooter, probably. As a collector--no.
