Found using this shotgun, swing through is not the optimal method..
Looked at the location looks like a (PTT then a Tree looking stamp?) the stampings were not in line so i did not pay a lot of attention to it.
These were located below the IMP CYL stamp sorry the Cal was a fat finger on my phone my apologies
The barrel I can confirm is a 26 in.
On the bottom of the barrel is the following an anchor, 2, ARR a 4 pointed star an N and an alignment mark.
The forehand guard has lots of checkering, the pistol grip has checkering on each side.
Hard plastic butt cover (looks like bakelite) with Remington stamped at the top(not a recoil pad for sure). I have to use a recoil pad in my shooting vest to shoot. Us old guys get to do that..
