I own a CP-16R and for the last few weeks I have been looking for core adapters for the magazine. The first port of call was whitehouseaudiovisual, but I don't know if they are defunct or just ignoring me as I have sent several emails requesting to purchase core adapters. Apart from whitehouse I can't find anywhere online that stocks Cinema Products parts and I'm in the UK so not in a movie hub with lots of spare parts going about. Does anyone know where I can get these?
