Added to the Davis collection with this Underfeed off ebay. I'm hoping my Minnesota A front slide plate will work for it and I have a shuttle in case its missing (hard to tell). I believe this was made around 1900 and according to my new old Excelsior sewing machine materials catalog from c. 1908, this is a Model H, which I've never heard of before.
