of dating an older - Dating spear jackson saws

There are several other WS medallions though (see pic below of medallions copied from the internet).

On the left, the shield is supported by the English Lion.

On the right it is supported by the Unicorn of Scotland.

As a result, I’m quietly confident that all of the medallions in the bottom row and the center medallion in the top row are from saws made in the United Kingdom.

I’ve never seen a medallion like the image top right which looks like a Knight on horseback.

Is there any way of dating this style medallion, or knowing what saw it came off of, or where it was made?
