old telphones (Harbourland ME14)

Hello, I have decided to introduce the concept of 'History' to my young class of special needs children through telephones, as I think I will be able to show quite a dramatic change over time with real artefacts that will intrigue them! So I wonder if any kind freeglers happen to have any old telephones that they would like to donate to me please? I would love to show them an old rotary style one, or even one like Mr Banks had in 'Mary Poppins'? Perhaps I can find an early mobile phone too? They don't need to be in working order. As I finish for summer soon, I will be able to collect at a time to suit you. Thank you for reading. Kind regards,
