I was given this machine a couple of weeks ago, and is it an odd one. There is a detailed thread on it over here
Kenmore Electric Rotary Sewing Machine or 120-49 is here.
So I won't add extra pictures, but the other thread is worth a look. The drive wheel had the worst flat spot I've ever seen, I should have taken a picture of it, and with the case the way it is covering the motor there's no way to lift the drive wheel off the hand wheel when not in use. I cut off the old one and covered it with a rubber tube, it works OK. It came with the dreaded (to me) CC1221 needle in place, which are very difficult to find. It also came with a couple of 15x1 needles loose in the table. Based on the needle eye/hook timing the CC1221 looked to be the proper needle, but I tried the 15x1 anyway, and it sewed just fine, in fact the stitches looked a little better than with the CC1221, so I've left the 15x1 in place.
It is noisy noisy noisy, and now I have to find some chain lube for my maintenance items!!
