How do I find the age of our Erde trailer?

I recently bought a secondhand trailer for my husband which he has completely refurbished. However, when I tried to insure it the insurance company were adamant that they needed the age of the trailer. Does anyone know how to find this out? I have the serial number. It is an Erde 121.

Google Erde and find out from them. There will be some kind of ID plate on it somewhere.
