BTW - if someone can take the width of the throat plate - the (round/flat) is the edge that hits the needle plate.
These are the Manufactures - not the Badged name, but this does help on US machines to figure out the actual Mfg. Some of the plates "sort of" fit others, but the needle plate is in a slightly different location so they do not line up right.
The Foley is 1.07" (round)
New Home is 1.209 (round)
Free (older) is 1.69" (Round) * later made Free were a copy of Singer
Eldredge (older) is 1.166 (round)
Seamstress (National that looks like a New Home) 1.166" (round)
National is 1.175" (round)
Davis is 1.185" (flat)
New Royal is 1.20" (flat)
White is 1.15" (flat)
Standard is so odd shaped that nothing is like it 1.152"
Household and Domestic (older) are oval, though I've not measured witdth yet *late made Domestic also a copy of Singer (cause that is what Sears wanted) however after White got the name, they are different again.
I've got three more I've not measured yet.
