According to a letter from Friedrich Emmel to Mr. v. Zeppelin, 28. April 1958, the construction of a new pocket watch with a quality between J38 and J41/J42 was ordered in 1928. Result was the J47, J48 and J49 which could be delivered 1930.

Junghans catalog 1931 text:
Bridge movement for hunting cases, thin model, 15 jewels, flat hair spring, lever escapement with visible jewels, double safety roller, gilt plates and bridges
G indicates a new click spring assembly from 1934.

The suffix /1 means that a seperate escapement wheel bridge/cock is used.
I assume that these watches are made from 1938 or later.
