I've got three of those GE Sewhandy's - and still no original pedal.
At least now I have three bobbins for it!
An interesting note - this takes the same standard attachments as my very early Standard Rotary (Yes, the Sewhandy is a Standard design).
Standard was bought by Osann, which was bought by Singer. It's one of the reasons it's thought of as a "pre-featherweight" because Singer did end up with control of the SewHandy name and design. However, other than the size, the FW and SewHandy aren't very similar. Singer did go on to use the SewHandy name.
