I just picked this up from a trash - sorry, antique - store. It appears to date from the first decade of the 20th century. It's missing the hand crank (the crank winds up a spring which turns the cylinder for the full 4 minute playing time - no electricity here) but it still works when turned by hand. Even without the horn (also missing) it's perfectly audible. The last two photos show the predecessor mechanism to the pause button. I bought it more as a display item than a functional piece, but I do plan on making a crank just so I can demonstrate it. Sadly, I can't seem to find any copies of Abbey Road on cylinder.
