I have a wingmaster that my father gave me for Christmas when I was 16, STILL a looks great and shoots better.
Almost EVERY police car in america has one of these locked in it's trunk or dash board. Not a wingmaster but same shot gun. Got one of those also.
Infact I have 6 870's ALL shoot great. Depending on the price, you had better pull the pin on that transaction and soon.
Nyother details on this, Gauge? Barrel Length? choke? most Wingmasters were made and sold prior to the remchokes so it might be Improved Cyl, Modified or even Full.
How much they asking? Hell I might just need another.
