[OT] Orginal Odhner 239

I know this is very much off topic, but perhaps someone has information or could direct me to a more suitable forum.
I have just bought an Orginal Odhner mechanical calculator at a thrift shop. I have been able to find out that it is a model 239, one of the latest models produced. Does anyone know how to find the age of the calculator from the serial number?
