Thank you, unfortunately my stinking camera is on the fritz! It was in A1 tip top perfect condition, given to me from my Aunt, it was hers. In the most beautiful art deco type of cabinet, Singer mode 15-91 prior to the fifties I believe, what a lovely machine, the whirring sound is so soothing and she sews perfectly. Anyway my aunt was a smoker and as I was cleaning it, I got alot of yellow on the cloth (thinking it was nicotine), I kept cleaning it until I realized that wait a minute, this can't be from smoke. So henceforth my search and finding out about the shellac finish...I should have never attempted this.....got the boiled linseed oil, denatured alcohol, shellac, appropriate cloth, and attempted to do this....what a mess.....trying that french polish method, can't get it right, took it off again, ruining my decals.......I'm simply crying!!
