Sure looks like a 65. Are you in a country in Europe? Has European proof marks and though is difficult to see clearly, some sort of police agency property mark on the left side of frame. Also before the 65 was introduced as a model, some police agencies special ordered 64’s chambered in 357 ( to my recollection I think the first American agency to do so was the Oklahoma Highway Patrol?)
In a similar vein, the NYSP special ordered model 10’s in 357 leading to the introduction of the model 13
