Brinn-Bradley-Kelvin Circus Ponies

I just bought this pair of circus ponies from Gayle Roller off eBay. She calls them Brimm-Bradley-Kelvin pieces and scanned some pages in from a reference book that showed them.

 Circus Ponies, Brimm-Bradley-Kelvin, $20, 7/2013, Gayle Roller.

 Clearly, they are copies of the Hagen Renaker Circus Ponies, but there were only two of those and I have seen at least six different poses of these.

One of my new ones isn't pictured. The tail-up isn't shown. Below is a picture pulled from eBay of another auction, and the circus pony with the arched neck is not shown in the book either.

The auction has an arched neck prancing horse that is not shown in the book above. (I do not own these pieces.)

 My newly acquired pieces are in the back in this picture. 

And my new walking pony is taller than my older one, although the pose is identical.

That puts the tally at eight different pieces that I know of. Betcha there are more than that out there!!
