I am in regular contact with Ed DiGulio, co-founder of the former Cinema
Products so when I saw this thread I sent him an email - his response is
below. Tiffen bought the assets of Cinema Products (out of bankruptcy)
back in late 2000 and they themselves just recently emerged from Chapter 11
(August 8th) so I think Ed's take is accurate. However, if you want to be
100% safe I would suggest contacting Ira Tiffen ([log in to unmask]) and
clearing it with him.
