Hi non-fixie, you have a very nice example of a Cyclo-Rosa chainring set. They work well with Stronglight 49D cranks.
Most I have seen are plated steel in 1/8" or 3/32" chain size. They were sold early on by Cyclo, possibly 1920's and certainly sold from the 30's through 50's. There were Alu versions also, but any I have seen were worn out.
Recent Stronglight 110BCD chainrings with a SunXCD spider are a good facsimile of these old Cyclo rings. See the pic of my Jack Taylor. I mistakenly identified the rings as TA, but I could see in my own picture that they are Stronglights.
