Recover lost .config

Is there a way to get or recover .config file which was used for building a running image?
A few months ago I built an image, which is running fine. It took a bit of time to prepare it. Now I would like to make a new built with current stable release. Unfortunately, I lost the repository within I compiled the currently working image. Is there a way to find the config.seed of a running image?

By default, no.

It is included if you have selected the build option to include config.seed in the firmware.

You can get the list of included packages with "opkg list-installed". But that tells you nothing about the possible config option changes.
