Instead of trying to unearth some Jewish connection with essentially Scottish Tartans and clans, I vote that a proper "Israeli" or Jewish tartan be submitted for approval in the afore mentioned Blue and White colors. That is if the interest is sufficient outside of this discussion.

That would be a stunning looking tartan if designed in an aesthetically pleasing sett, too.

As a foot note:
Like the "brother against brother" of many other wars, I wonder if these particular Glasgow Jewish soldiers in the WWI photo had to go up against the many German regiments staffed with Jewish/German soldiers in the first world war?

But then, that is another topic.
