Vintage from my mother's collection.  Not in the best condition, but appear to be functional.  Too bad I cannot find the original buttonholer, this was the best buttonholing device in my opinion. The newer versions don't seem to sew the buttonholes as fine or precisely as this one did. 

Included: 
1 1/2" or 38 mm
1 3/8" or 35mm
1 1/4" or 32 mm
1 1/16" or 27 mm
15/16" or 24mm
13/16" or 20mm
 metal tool, that I think was used to tighten something, but cannot remember.

Please see photos for the condition of the cams.   These items come from a non smoking but hypoallergenic dog household.

Thanks for shopping. Feel free to message me with any questions.

These ship USPS Priority mail, insured and I do ship out the same business day auction closes.
