Since the guns pictured are just a representative gun, the one you actually get may be better or worse. They are Pattern 1853 Enfields, made by various contractors, of at least two different types. Enfields were sent to many different countries. Since India was a British colony, many were sent there and quite a few ended up in the surrounding countries. Some folks are buying these guns to part out. CW Enfield collectors sometimes have a gun with missing barrel bands, butt plate etc. and the supply of CW era spare parts is pretty tight. Most of the parts from these Crapastan modles will fit some of the American CW enfields but the markings will probably be wrong.
If you want to buy a P-53 bayonet here is one place to go.
