WillyLeathers Report post Posted December 23, 2021 I am cleaning up a Mercury 111 H that has not been used in 10+ years. Does anyone have ideas on where to find a manual for this machine? Does the H stand for the bobbin size? I am wondering if I am able to change bobbin size by putting in a new larger rotary hook, the one standard for a Sailrite 111. Thanks, Willy Quote Share this post Link to post Share on other sites
chrisash Report post Posted December 24, 2021 Is it a clone of the Singer 11 series, I know nothing about the Mercury machines, but many clones use the same model number, your best bet it to look at some photo's of the singer 111 series and company them to your model. Tons of information on the singer 111 series Quote Share this post Link to post Share on other sites
Wizcrafts Report post Posted December 24, 2021 Using Google image search I saw Mercury M111 machines that were straight stitch tailoring machines and some that were walking foot machines. The company has been out of existence since about the year 2000. The availability of parts or any manuals will depend on exactly which major brand and model is was a clone of. Buying off brands is risky, especially if the company is out of business. Quote Share this post Link to post Share on other sites
