Those are some nice machines. I especially like the Model 66 with the Lotus decals.
The Franklin was made by Domestic Sewing Machine Co. for Sears. It's a copy of the Singer 27 made circa 1911 or so. It uses Singer shuttles, bobbins, regular 15x1 needles and mine sews very nicely.
I've yet to find an actual model number associated with that machine, still looking. Mine's in a parlor cabinet. It's a rescue from Good Will in Terre Haute, IN.
You won't find anyone here that will help you "downsize" your collection. We're all enablers and collectors ourselves.
Myself .... ummm ...... well ... ahh ..... I think I might have around 60 or right now. But they're not all in the same place so I cant really count them.
Sometimes I think they're breeding cos I keep finding ones I don't remember.
