Thanks for that. Did that go on in place of the feed dog, or was it a separate part? I'm guessing it went on with the slot perpendicular to the needle travel? YES
The 97's came with one,they were only a needlefeed machine w/a jump foot & they had different sizes too.It mounted different on the 97 but the same principle,the biggest difference is the feed on the 97 just went front to back & the 441 also goes up & down so there's not alot of room for error when making one for a 441.
The machines Ferdco put these on had a jump foot(where the needle only is feeding)& the foot lifts,the 441's have the center foot that goes back(and help pull) with the needle & I really doubt if there would be much benefit in using it.
