Antique miniature wooden ribbon weaving loom. c1920.

I have no knowledge of ribbon weaving, I picked this up because I loved how smooth the wood was! Selling untested. I don’t know if this is complete or if any parts are missing. 

Super soft, worn wood construction, with metal working parts (all a bit pitted or rusty). There is some string to the inside. I don’t know if this is functional.
