Pentax 6X7 instant film filmback: What film size it uses?

[calacaroja]

Hi..

I got a mint FORSCHER POLAROID PROBACK FILMBACKwithout instructions for a Pentax 6X7.

Does someone knows what particular Polaroid film size it used?

Just wondering, to see if Fuji is still making the right film size for it.

Appreciate any information that might help me use it if is still possible.

Best, Alvin

Most likely the Polariod 600 series packs, with film such as 669, 667.

A quick google suggests it's the standard type 100 (that's what it's actually called, Type-600 is integral film). This would be like Fuji's FP-100C or FP-100B or FP-3000B etc pack film.
