As a possible extension of the Harman special sheet film production scheme, is there any interest in something similar in FP4/HP5 in 70mm perforated?

Having run it past the planners at Harman, they are prepared to cut it as a special order for Silverprint. We would have to order a minimum of 60 cans of 30 metres, in either film type, and keeping it priced as competitively as possible it would sell at 80.00 + VAT per roll. This price is not significantly more than the equivalent sq. metres in 35mm 30 metres, so Harman are being supportive here. We would take a chance in holding some stock, but would like around 60-70% of it covered with committed orders to go ahead.

When we first discussed it, Simon Galley estimated it would need a 20-30k order to kick it off - this then came down to 120 cans, so 60 cans is a big concession from Harman. So is there enough of a user base in 70mm to keep a regular supply of the format on tap, in very popular emulsions? We await the response with interest.
