Up for auction with no reserve is a vintage 1890's music box disc.  The disc is made of metal.  There is some wear and tear to the finish from age and use and it may be bent a little. The drive holes and tabs look to be good. It is untested as I do not have a music box to play it on and it is selling as pictured.  I am told that this disc can be played on both Regina and Polyphon music boxes that play 15 1/2" discs.   It measures 15 1/2" in diameter.   I always combine shipping when I can safely do so. Please look at my other items that I have for sale. Thank you and have a great day :)
