Standard rotary treadle bobbin holder hunt.
 

Please anyone who owns a 1904 Standard rotary,
If you would please post a pic of the bobbin holder both sides and bobbin if possible. I have ordered several that said they where for my machine but was not. My bobbin holder is rounder but shallow. I thought I had found a winner from a box of attachments perfect size but wouldn't fit over male part in bobbin housing. So if someone could just show a pic of both sides of the holder I would be so happy, Or if any of you experts know of a bobbin holder that would work in the originals place that would be great.
