Does anyone know what coating (if any) a pair of 1972 15x60's would have?
Thanks in advance.

At least single coated, maybe multicoated?? Prisms coated?

My Zeiss archival info says that generation has T coating, Zeiss's proprietary coating. That I believe means it is multi-coated.

I think T* is the West German Zeiss marking designating a multi-coated anti-reflection coating. The T marking is a Zeiss Jena marking for its first single layer coating (T = Transparenzbelag) often present on their WW II Kriegsmarine binoculars. It looks very much like Zeiss West Germany introduced their first multi-coating for binocular in 1978 (see Henry Link's comments: http://www.cloudynights.com/topic/522211-educate-me-on-vintageexpensive-wwii-binoculars/ ) so if Trancework's binocular was made in 1972 it would be single layer coated.

Hi,

yes, T coating means single, T* means multicoated. Both designations were mainly used by Zeiss Oberkochen, CZJ marked coated photo lenses with a T until 1956.

My 15x60 c.1965 has single coatings on the objectives, prisms and eyepieces.
However, there is one uncoated surface in both eyepieces, which may or may not be due to the factory cleaning.

P.S.
It may be that the rear surfaces of the eyelenses is deliberately left uncoated.
