Chris, you are not correct about the ZM/Z line only refering to the scopes made in the USA. Please understand that I am not trying to argue with you but am only trying to understand what Zeiss has done with their scopes. I am looking at a catalog that I have kept from the mid 90s prior to the VM/V being produced. The scopes listed in the catalog were the
Diatal ZM/Z 6x 42 T* Made in Germany
Diatal ZM/Z 8x56 T* Made in Germany
Diavari ZM/Z 1.25-4x24 T* Made in Germany
Diavari ZM/Z 1.5-6x42 T* Made in Germany
Diavari ZM/Z 2.5-10x 48 T* Made in Germany
Diavari ZM/Z 3-12x56 T* Made in Germany
Diavari C 3-9x36 MC Made in USA
I believe this catalog was printed around 95 or 96 when the 3-9x36 was moved to the USA. Prior to that it was made in Germany. When the VM/V line was created, the entire line of ZM/Z was moved to the USA and changed to MC coating instead of T*. I am pretty clear on this. I also have a catalog printed in the late 90s after Zeiss moved the ZM/Z line to the USA and the only noticable difference is that the ZM/Z have MC coatings instead of T* coatings, but the line and dimensions are exactly the same. What confuses me is that the "Classic" line listed on Zeiss UK website doesn't fit the dimensions of the ZM/Z line or the VM/V line. I have checked the length and weight of each scope and they don't match any of the scopes. Although the pictures listed on the site are of the ZM/Z made in USA. I will give you an example of what I am talking about and the approximte time that I believe they were produced.
Length Weight Era
Zeiss Diavari ZM/Z 1.5-6x42 T* Made in Germany 12.6" 19.8oz.   ; 1990-96
Zeiss Diavari ZM/Z 1.5-6 x42 MC Made in USA &nb sp; 12.6" &nbs p; 19.8oz 1996-01
Zeiss Diavari VM/V 1.5-6x42 T* Made in Germany 12.29"  ; 14.2oz. 1997-pres
Zeiss Classic Line 1.5-6x42 T* Made in Germany 12.8" 16.9oz. ?
In other words, Zeiss had the ZM/Z line made in Germany with T* coatings and moved production of the ZM/Z to the USA when they came out with the VM/V. However the ZM/Z was the same dimesions as it was when it was made in Germany, just different coatings. But what is the "Classic" line. Also as far as I can tell, they never had a 2.5-10x50 ZM/Z or Classic or anything else. Back in the Eighties they had a 2.5-10x52 and then a 2.5-10x48 in the 90s. Then they finally came out with a 2.5-10x50 VM/V in the late 90s. However what is a 2.5-10x50 "Classic" line. Either this is a website misprint or they have created a new line of scopes in Europe but didn't tell anyone. Again, I am not trying to be arguementative but just want to be clear and have my facts straight. I am a little confused on what Zeiss has done.
