Small bronze horse / signature assistance

Hello Antiquers-
I have a small bronze I'm hoping to learn more about. Specifically who the artist may have been.
It's about 16cm or 6" tall and has 5 distinct marks.

Photo #3 depicts what I believe are the initials "RK".
Photo #4 depicts what I believe is the year "1976"
Photo #5 depicts a signature or other word that I cannot distinguish.
Photo #6 depicts what I believe is the number "4".
Photo #7 depicts a character that is not familiar to me.

I would appreciate any insight and/or opinions on the work.
Thanks Antiquers!

 

In the area shown on picture #5, take a flashlight and move it slowly around, all angles. This may help you see the form of the letters.

It may be the foundry name, the title, or simply say bronze.

James.

 

Apologies I cannot help with the identification, but it's lovely!

 

Thank you James. Cheers Antidiem.
Try as I might, I'm not able to make out the signature in photo #5.
This is my first bronze and I'm trying to learn what I can.
Is it at all unusual that a piece is marked in 5 distinct places? I've not seen this before.
Thank you again.
