31 model a question

Can someone tell me what this ring was for? Had one on both sides. Was it original? Thanks.

 

I know it's not original but I have no idea what it would have been used for.

 

My guess would be to tie the christmas tree to the roof?

 

mabe to tie the horse on to take along side?
they did alot of modifications just for everyday function then for beauty.

 

My thoughts exactly!

 

it's a nose ring like in who nose what it is for

 

Don,t think you will be getting the correct answer this year
