Hello, my name is Greg.
I am trying to get a visual of the bed to try to determine this for you. Can you take a picture from various angles - especially in any area where the paint is chipping (or rubbing)?
Thanks for the uploads. Give me a bit to look them over and see if I can track down anything in my resources. Be back shortly.
Thanks for uploading. Based just on the pictures (without being able to visually see the items myself to really inspect the surface), I would think that this looks like an original brass finish. These look to be from early to mid twentieth century (although not able to find exact match in my files quickly). Is there anything identifying on them? Very nice set.
I was just wanting to reach out to see if you needed any additional followup on this question. Feel free to reach out if needed.
When satisfied, be sure to rate my response so that I receive credit for my help on this question.
Have a wonderful week.
