AHM Accessories For Model Railroading Enjoyment Bridge‎ Track 2910

AHM Accessories For Model Railroading Enjoyment Bridge Track 2910. These pieces are in a box and appear to be new but the box that they are in says it is a caboose 5340 P spirit of 76 but I do not believe that's the case. It is just the tracks shown in the pictures. It appears to possibly be item number 2590B deck bridge unassembled.
