Heritage Sea Dart info needed.

Okay, Heritage and/or just Sea Dart owners.

Where can I find the serial number?

I have a really old Heritage Sea Dart 14 and I don’t see the serial number on any of the outside edges as I do on my Old Town kayaks.

Any info is appreciated.

Hmmmm never thought about it.
I’ve never noticed where it is. I don’t use mine much the last few years.
