Indians For Guns

Hi everyone,
Planing to buy a fn trombone. Rifle is in good condition blued but everything is original from the front sight to the stock plate. I have used bolt action rifles before but not a pump action rifle, so now I am thinking whether to buy it or not " please advice "

Please share the pictures and other details

If the seller allows, try shooting with it and see if you like it. Offer to pay for the ammo.
