Breeding Treadles

(They need privacy, but I hope these two will make an industrial ZZ between them)
Singer Improved manufacturing, probably from about 1880. In it's original treadle and from the son of its long-time user (probably not from new)

Elegant ironwork

And, my birthday present to myself, a Singer 216g zigzag treadle.. It came with a horrid motor, which we discarded

School-house treadle.. 1950s, so about my age

Decals from the 216g. I don't think these are on any other models
