G’day, I am posting from Australia. I am trying to get an idea of the cost/value of a CP16 camera dating from the early ‘70’s. I am intending to purchase one as a display unit. It doesn’t run and all the rubbers are shot but it has some interesting provenance. The seller has no idea what it might be worth. I noted an earlier post where a guy said he got one for $1300 (US or Canadian$ ?) presumably in working order. Any ideas out there? Thanks in anticipation.
