I also have the same cue rack, but mine has a chalk board in the bottom 1/4 with the top 3/4ths bevelled mirror--
I bought mine in Axtell, Kansas about 20 years ago. I would date the cue rack in the early 1910 to 1920--
WOW!!!! That thing is huge. I think it will be beautiful once it is refinished. I have an 1924 side loading Brunswick ball rack that I am almost done sanding. I will be watching this post to hopefully get some restoration advise.
I would suggest contacting the people at the following address. They can tell you what you need to know about your rack. A phone number and address is on their site.
