the black one is my Grannie's old machine. It was badged Royal on the front but it came off. I added the handcrank to it when the cord became dry rotted going to the motor. Dh says he will repair it one day.....
The 2nd one is one I got off freecycle. It sews wonderfully but has the left needle position which makes it kind of odd.
The third one is the machine dh just brought me today. I know nothing about it except that it runs. I'm wondering if class 15 bobbins will work in it?
The only one I don't have a good picture of is my Singer 127 treadle. The decals are all silvered on it so it doesn't look great. I hopefully have found a redeye though that looks good to put in my treadle base.
