Mauthe mechanical clocks

Hi, i am really happy to find this forum. This clock is belong to my grandfather that already passed away in 1999. I found that my clock is somehow same model with this thresd starter.

I ask my mother about this clock and she remember that the clock might already bought around 1962. According to the logo design, it seems to be produced after 1946. But i just found out that in the dial it have logo that show it produced before that. Can you guys help me to narrow this clock estimate time of production? Really appreciate your support
