The Covenanters carried this banner into battle. The Reformed Presbyterian Church has continued to use these banners in their churches.
I have not been able to find any vector versions of the blue banner. And using the current design across various mediums can be challenging with the current design.

These initial vectorization allows for the image to be scaled. But the finer details make it impossible to use at smaller sizes.

This more stylized version simplifies and attempts to modernize the banner.
