Question from DeDe about Gramma's Sewing Machine

I'm in France at the moment where I just bought a vintage 1930's Singer Treadle sewing machine. It reminds me so much of Gramma's that I wondered if the Aunts ,or anyone else, (Vicki?) knew what year Gramma's machine was??

Also I remember a story about Gramma sewing over her finger- was this just a warning to scare me away from her machine??

Also who has experience with this treadle thingy- I need tips to make it run more smoothly.

Thanks for the help.
See you soon.
