HELP NEEDED IDENTIFYING A DULCEPHONE

Hi, could anyone please help I am about to buy my first gramophone but am uncertain if the one I am currently looking at is a original or a replica !
I have tried to find info on the net but do not seem to find this exact one, being new to collecting I am afraid of buying a replica and not the real thing.
I have attache the photos I received from the seller, and have been told that it is an original from the early 1900's ??????
Any information on this item will be greatly appreciated !
