Boar Boyz shields

[BapsZerg]

I have started painting after a 14 year break... Surprisingly, I managed to salvage 80% of my old paints.

Now I have a dilemna, as I have misplaced the majority of shields for my Orc Boar Boyz. I purchased both shield bitz from Games Workshop, but neither are suitable or to my liking. The original shields are the larger (though small by today's standards) round type.

Any suggestions of a method to obtain similar shileds to the originals?
