Okay, this is a link to a list of dealers (it's located in an old packing shed, one of about fifty little shops under the one roof):

http://www.tyabbpackinghouseantiques...s/Dealers.html Jack's Cameras is listed about two thirds of the way down the page, and here's the phone number: 03 5977 4414 You need to ask to speak to Jack Ross. They're open Thursday to Sunday and all public holidays except Good Friday and Christmas Day.
Good Luck!
