That is not a Marlin Premier Mark I French built shotgun. The Mark I made in France for Marlin in the mid 1950s had above average wood and finish. They are some what scarce but not expensive. I think Marlin only made about 3,500 28" 12 Ga. guns. In X-Lent condition they go for around $250 bucks.
There are a lot of guns that cost a lot more than a Mossberg 500 that wish they were as reliable. If you decide to buy any new shotgun put it together so you are sure that everything lines up before you accept it. QC is not what it should be for any gun company.
I have Mossberg 500's that I have had for over 20 years that I bought used. I shoot skeet with a 20 ga 500. I used to shoot a lot of skeet. I would shoot 400 rounds every weekend with a mossberg 500. The only parts that wore out were the interrupter and the shell stop.
I think the old mossberg 500 are 10x stronger made guns then the ones that come out now. The wood and metal just feels cheaper on the new ones. I'm kinda holdin out for an older one
