I have also posted about the American #7 Handcrank that I got (and Cathy has posted about her #7 Treadle head)
They use a version of this shuttle but without the "dogleg". it is straight. Same bobbin
EDIT: Yes, the harp space is cool, but the real "claim to fame" on this is it's "punching power". The handwheel weighs 2x what the #1 unit's does. and the needlebar is about 20% thicker.
