Yes, handling is quite similar to old Polaroid Type 55.
The holder is the same (Polaroid 545 Land Film Holder).
During the late prototype phase, development time was 2 minutes. It may differ in the final product.
We are not sure if the print will require the acetic acid coater or not. That will only be determined later in the selection of the receiver sheet material; but the negative does require fixing right after development.
We used Ilford Rapid Fixer with highly satisfactory results. The old sodium sulfite bath is optional.
