1 Points, Typewriter Hunter

I'm a grandmother who just recently bought a Smith-Corona Silent (Type 5) manual typewriter. I was inspired to buy one from watching the "California Typewriter" documentary. I've always loved typing, so this is a really fun project for me. I've cleaned and oiled it and am just waiting for my new ribbon from Ribbons Unlimited to be delivered so I can use it!
My machine's serial number is: 5S124609 which is earlier than the number you have listed in the database for my machine. It was labeled as a 1953 machine, but I'm wondering if it's actually a 1949 machine? Thank you!
