Please help to ID the maker and date

[marylander]

I bought a wall regulator clock last weekend. The clock appears to be a German clock. But the movement and dial do not show any logo. Here I attached a few photos of the movement. Hope the movement maker is identifiable. Thank you in advance.

Hi,
It looks to me that your clock was made by Kienzle.
Regards.

FMS.Friedrich Mauthe Schwenningen. After 1890.

Here's Mauthe with complete escapement protection (Kielmann's patent DRP 55006). Compare hands, shape of the back plate..

Thank you both Piotr and Ticktocktime for your help. It looks to me that my clock movement is very similar to that of FMS.
I will show a photo of the complete clock later. The clock has been cleaned and lubed. It is working fine now. The photos shown are before the cleaning.

Please let me know if these together with the series number in the previous photos help to date more closely.
Thanks,
