Yes to the cleaning/oiling. When we first started on her the dogs were stuck in the down position so the mechanism that involves the stitch length/feed dogs height was oiled and scraped off (am sure there is more debris there but it seems to move freely) but the stitch length remains the same.
"Tight" is a misnomer ------ "impossibly tight" would be a better description BUT she sews with the tension like that!
The spooler is a removable object that slips into a holder on the leg of the irons - at first I hadn't a clue as to what that thing could be but figured it out pretty quick. Needless to say - even though she is a simple machine, she's sooooo interesting to fool around with. Hope she's going to be a super working girl ............ ;o)
Yours is so pretty that I'm entertaining thoughts of having my younger daughter do some decorative painting on the machine (she does lovely work) as this girl is Plain Jane. Will that destroy her antique value in any way???
