I have an elna "automatic"
Ive never taken it apart but if you need pics or anything I could take some and send them to you ,.I did take the nose off of my domestic 153 and what a bear that was to put back together ugh! it had this actuator that crossed over from the needle bar to an arm on the other side ,never thought id get it back together lol .good luck!
and remember when to walk away and come back later Ive had a few of those moments.
