Need help with old machines for stitching soles and outsoles

[Pyrka]

Greetings from Ukraine! The other day, my father and I bought 2 old machines for stitching soles, I'll attach link on photos from market below (sorry, idk how to attach them another way):

1. Machine #1: https://www.olx.ua/d/uk/obyavlenie/shveynaya-mashina-gottwaldov-03028-p11-doppel-IDXfCc7.html

2. Machine #2: https://www.olx.ua/d/uk/obyavlenie/shveynaya-mashina-due-fili-bj-65-doppel-IDXfBZT.html

 

These beasts are over 50 years old! The mechanism is working, but there is no instruction manual. We do not want to spoil the machines, we still have a lot of work for them!

Perhaps someone can help us find instructions for their care and use?
I will be very grateful for any information

See some info here.  https://leatherworker.net/forum/topic/15122-how-to-post-pictures-on-lw/

 

Please avoid using 3rd party hosting as those pictures go missing when owner moves or deetes files, or the host decides to change policies.  The the post becomes useless.

Many members will not view unknown sites so would not be able to help provide the information you are asking for.

Thank you!

The question of machines is still relevant
