Just had a brand new 17mm Nagler delivered and I am very suprised to see that it has been made in Taiwan! So I checked my 22mm Nagler and yes that is also made in Taiwan. Since when has this happened?

having trouble finding a date of when this occured but managed to dig up the below......

The prototype Nagler eyepiece was manufactured with a focal length of 13.1mm. These prototype 13mm Nagler eyepieces were all made in the United States and air spaced elements were multi layer anti reflection coated. However, Mr. Nagler noting the high cost of production in the U.S. compared to the costs overseas and aware of the ability of Japanese manufacturers to consistently manufacture small lenses to very stringent specifications, decided the future production Nagler models would be made in Japan, and some models would eventually be made in Taiwan.
