The intermediate stamp replaces the former block of Arabic text with some sort of gibberish symbols. The English component of this stamp always seems to have some stamping problem, so it is often illegible.
It is not Arabic, unless it is the Comic Sans font for Arabic(? The distinguishing feature is the combination of the small-sized star in the crescent with the non-standard symbols where one would expect the Arabic.
The first stamp that included the word “Istanbul” used a tall narrow font, and eliminated the word “trademark” which had appeared on earlier stamps under the word Constantinople.
Ironically, the Arabic text translates to “Avedis Zildjian” while the English says “K Zildjian & Co.” and this is the same combo of Arabic and English that the Zildjian company uses today.This is the only stamp with this arabic script and the spread out “Made in Turkey.”This 16″ cymbal has a lathing pattern sometimes seen on cymbals from this era, where the tonal grooves are clustered closer together, then spread apart in concentric circles. This image, from a polished cymbal, provides the most detailed image of the Arabic, while the star above the crescent is missing.Still, the tight wrapping of the words “Made in Turkey” identify it as IVb.This stamp is almost identical to IIa except that it has a big K.The word “Zildjian” is top-aligned with the K, as though it were a superscript.The so-called new stamp looks very similar to the intermediate stamp, with the main difference being the size and location of the star above the crescent moon.Also, the stamp seemed to imprint the English more thoroughly than with the intermediate stamp, but there is often double stamping, as the cymbalsmiths pressed the stamp twice by hand.It should also be mentioned that these are also often referred to as Stamp III because of the big K.In fact, that might even be more common than calling it IIb.A Zildjian Stamp Timeline Chinese Cymbals G Zildjian Cymbal Mystery Italian (UFIP) Cymbals K Zildjian - Canada & US Timeline K Zildjian - Constantinople Timeline K Zildjian - Istanbul Timeline Stamp Anomalies (new) The (Avedis) Zildjian company started making K Zildjian cymbals in a factory in Medutic, Canada in 1977.They brought a few cymbalsmiths from Istanbul to Canada at the time. Later in 1979, Avedis Armand Zildjian and his cousin Mikhail Zilcan both died, and everything changed. Within a few years the Canadian factory would be producing Sabians, and the A Zildjian Company would make K Zildjians in Norwell, Massachusetts.
