Harvey House Restaurant Counter Chairs

I have done some research on the internet and have links to photos of these seats in Harvey Houses; one photo is from the Fray Marcos Hotel Harvey House in Williams, AZ:

the second is from a Harvey Girls website but the photo does not give a location:

I have attached a photo of one of the chairs, there are a total of four.  The pedestals appear to be iron and my uncle had spray painted them black.  The seats themselves may be bronze, I will leave that to you viewers.  I love the little pins on the pedestals, which I assume were for your hat. 

Would appreciate any opinions on these.  I have enjoyed what I have learned about Fred Harvey, his restaurants and the Harvey Girls...I even caught the movie musical "Harvey Girls" starring Judy Garland on TV! 

Thanks!!
