Hello
The reason the clerk told you that it was a special gun was that it has adjustable sights and most model 36's all came with fixed sights. The chiefs special target versions were marked 36-1 and as the model 50 at Random and with a very Limited Production. they made them from 1950-1999 and the total Production of them was 1,740. I assume yours is the later model which came back out In 1989 and this model was the 36-6 with a full Lug Barrel. It is worth having factory lettered and can bring as much as a Third more in Value than a standard fixed sight model 36. These target specials were made in the later dash-6 series from 1989-1990 only according to my reference Information. I hope this helps, Hammerdown
