Around What Time Did Kyocera Manufacture The Contax TVS

[fullrun]

I am trying to find out when my Contax TVS (first version) was manufactured. The only numbers that I spot on the camera are:

077778

I would even be satisfied knowing approximately when the first TVS version was manufactured. Thank you beforehand.

Any clues would be greatly appreciated.

Is it the film or digital version?

it's the film version, I gave an approximation on it in another thread by this user
