Have an ex-police issue Winchester Model 1200 with an attached ventilated guard suited to the M-5 Garandicon bayonet. Purchased it at Houston Texas gun show back in 1987 when the police were still allowed to peddle their used shotguns back to the civvie market. As I remember, the shotgun I purchased originated from a small police department in south Texas. Also picked up a Stevens Model 620 with ventilated guard for $120.00 and Stevens Model 520-30 riot gun in newish condition for 150 dollars more from the same dealer. Nice WWII issue Model 97 Winchester trench guns were also available for 350 dollars each but were too expensive for my budget. Ah, those were the days!!!!
