what a great cabinet. i just took one to my church that had been donated for our sewing group. it is perfect as is the machine that it was made for. a VIKING HUSQAVARNA. top of the line. from the book that came with the machine i'd say it is early to mid 70's. isn't the cabinet handy? and solid wood.
wish i could offer tips on making your machine fit. i'll bet someone who is a wood worker/cabinet maker could retrofit for you. good luck.
