I have a rare piece of solid oak vintage furniture that none of the experts I have approached can adequately identify or give a name for. If anyone would allow me to pick their brains, I would be most grateful. I suggest it as 'rare' as thus far I have been unable to find anything remotely like it on the Internet I was hoping someone could possibly suggest what it is. Likely to be early 1900s convertable bookcase to low tabel. It has three functions, table, bookshelves and display unit. It converts in a second or two from a 5 shelf bookcase/display to a low (18" high) table. It has a black metal 6 position locking mechanism that works perfectly. Overall 25.5" width x 32.25" height x 14.5" depth. The shelves are 22" length x 6.75" width. In excellent condition. Any suggestion would be welcome
