I looked at the three I have, and two are about as worn as yours.
It's neat looking at the Boye Shuttle chart, it helps to give a guide as to which MFG made what machine, since New Home, Davis, National, Goodrich put all sorts of Names on their machines. Standard and White also did, but not to such an extent.
But you also have to be careful, because they often used the same name. I've seen Favorite used on both New Home and Standard, and New Queen that was used on both White and National - and there are others too. And not every name is on this list - as some times the MFG would put some local Dealers name, and there were very few made with that decal put on it.
