Need Help To Identify An Old Adler Leather/shoemaker Sewing Maschine

[Lars P]

Hello from Germany

I hope that I might find help here. I got a couple of old sewing machines from a saddlery resolution. Most of the machines I could identify. Just three of them i don´t know.

-There's an old Adler, probably from 1930-1950? There is no label except: "Adler" + " Betema" serial number 159062"

But "betema" is probably just an advertising sticker i guess. It is in good condition, photos are just slightly bad. I would like to build it up, but need a model number to search for parts and manuals.

Maybe some of you have seen it before.

-The second machine has unfortunately no names, probably of 1950-1960?

And the third machine is probably a form of press / roller for leather belt? The mold can be heated and leather belt is pressed between two steel jaws in a form? I guess only. Name: Astor 24

Thank you for any tip

Damn, I would like to know myself! Never seen Adler equipment quite like that first black machine.
