48T and 36T chainrings are original M952 ones. 48T had huge wear, but was "refurbished" by my friend using some sort of a cutter. 36T is in better shape. 26T chairing is not original but Sugino one.
Sorry I didn't test them myself because I sold the spyder. Probably the middle is good enough for a new chain (the previuous owner mostly used big gears), but the outer... not really sure.
