Early Goerz Lynkeioskop. Year of manufacture?

Hi,

Would anyone be able to estimate the year of manufacture for Goerz Extra Rapid Lynkeioskop, Serie C no. 4, serial# 3894?
I would have to assume it is close to 1890 (when it was designed) but I have failed to find information about how many of these were
manufactured in early production years.

Thanks for your help,
Janne

Certainly early 1890's. There are no lists of the early Goerz serial numbers. Lynkeioskop was quite a success and the series C was continued until 1914 at least.
The series III already in production by this serial number, unless Goerz reserved batches of serial numbers for particular products.
