Hi Tony, I looked up in the book The devided Circle by J.A. Bennett. I didn't find Barda but Borda. In your second mail you metioned this name. There is a picture of a Bordan type reflecting circle by Secretian, mid 19th century, radius 135 mm. As written the instrument might be named a reflecting circle or even a repeating reflecting circle.
Could this be of help? Best, Fer.
