I found an old drafting table in my garage

Hi! I recently found out my dad had a drafting table(although he used it only for painting) and became interested once I found out I could configure it to my liking. Up until then it stayed in my garage collecting dust. I wondered if anyone could help me configure the table so I can adjust the height and the angle using the pedal of the table. I researched a bit about the table and it seems it’s from the 50’s Germany by Franz Kuhlmann. On facebook I think I found the exact model where the person is adjusting both angle and height using the pedal. There are 4 screws that are used for adjusting the table manually. I’ve managed to configure it so that I can change the angle of the table using the pedal. I could of course tighten the screws to fixate it, but I was wondering if it would be possible to change both the angle and height using the pedal. Thank you for help 🙂
