There is a article on the web that explains the 4 basic variations of the pistol. I have a link somewhere that I will try and find and post on here
With regard to the crinkle finish, the early models were chemically blacked as stated. Generally these also have an adjustable trigger but a very heavy trigger pull weight of the order of 1500 gms.
The crinkle finish was adopted to reduce costs, not only because it may have been cheaper to apply, but also it reduced the reject rate of the bodies that showed surface flaws, (porosity, tears, slag inclusings in the cast)
The body also did not need the same degree of preparation for the paint application
Non adjustable triggers are usually between 550 and 750 gms pull weight and so are more suitable for target shooting
