Pathé Actuelle Model T Tudor English Gothic Phonograph

[colmike1]

I have a client who has a Pathé Actuelle Model T Tudor English Gothic Phonograph. It is in excellent, original condition. I am trying to figure out fair market value for them. More than likely I will be bringing it to the APS show in Schaumburg. Looking forward to hearing everyone's opinions! Thanks.

Anyone have any ideas? If I cannot give my clients a range of value, they probably will not allow me to bring it to the show. Unfortunately there has not been one sold in recent memory to use as a comparable. Any help would be appreciated. Thanks.
