Any info about the manufacturer S $ S

I told a friend I would help her research her propeller and so far not much?
90" walnut propeller with an emblem that looks like wings with S & S in the middle of a red circle. both ends are fabricated yellow on metal and there are 8 holes in the center. I cant really make out the letters and numbers but there are 3 round imprints one on top of the other as well as SER.H. Can anyone help me with this?

That's not enough information to identify any propeller, but if you want to play the odds game, it's an S&S Propeller manufactured in Winnipeg and used on an Avro Anson airplane.

You'd really need to know the stamped drawing numbers to know exactly, but search on this forum under Advanced Search using keywords "S & S Winnipeg" and you'll dig up a lot of threads on them. You may be able to infer the numbers even if they aren't completely legible.
