Thank you Pudly. Snuffy33 I am not sure where that is.
Thank you 451_Detonics. So I did some extreme digging and just found the manual. So we can learn more about this gun together. The * on the barrel legend (*-Full Choke, **-Modified Choke, ***-Improved Choke, ****-Skeet Bore, No Mark-Cylinder Bore). Looking through the parts list in the manual I go to Modified Choke Delux 28", look across to CAT. No. 8133, Model K-121. So I head to Blue Book of gun values (thank you again) and find out it was made between 1966-1972. then I notice that the manual was 2/72. So basically I found info. I still thank everyone for all their help. I think I may have a junk gun cause the barrel is not 28" anymore, the buttstock is cut down as well, the shell chamber is extremely loose, the pump slide is extremely loose, the magazine spring is week and I don't feel like fixing everything to have a $100 dollar gun. It doesn't even look mantle worthy. I am just wondering if I should sell it to an unsuspecting person for $100 and be done with it.
