Vintage Chainstitch Embroidery machine

I’m on the hunt for a couple machines. Looking for the vintage style Chainstitch embroidery machine ex Singer 114w103. These are the hand guided machines, no computers involved.
Im also looking for a postbed version of this machine probably a cornely or lintz machine.

I know some of you all with older embroidery and screenprint shops had these earlier on. Maybe they are collecting dust in your shop and you’re lotto get rid of them ?

Please let me know.
