Identify a 4x5 film holder for developing

[gsuser]

I just picked up a super deal on a large format darkroom with enlargers, Jobo CPP2, drums and everything else needed for printing. There is one item that appears to be a film holder for 4x5 film developing. That I can not find anything in all the boxes that would hold this reel.

This holds 4x5 film very nicely only touching the edges and holds 10 sheets. It is a little to big to fit in a Jobo 2820/2870 drum. omebody out there must know about this so thanks in advance.

Never seen one of those.

I guess it's for old Polaroid 'clearing'.

Whatever that is!

Thanks, and I just found an image of the Polaroid tank/bucket with the negative holder and that is it.

This is from a polaroid dip and dunk clearing tank for P/N film.

Yup, for a clearing tank for type 55 Positive/Negative film - had one myself once upon a time. It neutralizes/removes all the "almost exhausted" chemical gunk that sticks to the film post development. I would up just doing it in trays.
