a few weeks ago a Thornton and Pickard Triple Imperial Extension camera came into my possession. it is in excellent condition. Also 3 plate holders, which don;t seem to be for this camera. There are about 3 or 4 mm too small. I need someone to identify what model it is. I am unable to, at this time, upload the photos of this camera, but can send them via email to anyone who is able to help me out. I am new to the camera and computer game but i am learning (slowly!). if you could help me out please let me know. Thank you, Murray.
