There is a big difference between stamping Turkish cymbal , or Turkish style or Genuine Turkish cymbal and Made in Turkey . By the time this cymbal was made and I am thinking 1930's, most countries in the western world had laws , requiring the country of origin to be marked on the item itself or the packaging. In the U.S. , spurred on by the huge trade in violins from Bohemia( German-Czech border area-over 14,000,000 instruments came out of there, in about 50 years) labelled Stradivarius, Amati, Maggini or whatever, a law was passed called the Mckinley law in 1891 subsequently called the truth in labelling law requiring all imported goods to be labelled with the country of origin. Yes, hammering style has similarities within a certain theatre of activity but it isn't the be all and end all of a mystery cymbals origin. It also has to do with the hammerer and the company.
The other thing is; yes the Italian cymbal makers have a history of marketing cymbals under a plethora of names and styles and many of their customers ( Gretsch ,notably), chose to classify and identify them as Turkish or Turkish style but I haven't ever seen one that says Made in Turkey. Usually, that means, where it is made . If someone was going to put a fraudulent country of origin on a cymbal, why would they use an unknown brand name? Wouldn't they go for the jugular and just put K.Zildjian on it and do it right?
