I'm still cleaning out and just found this stuff. I got these in a trade with Jim Galli a few years back and have no idea if they are of any use to anyone or not.
One is a 545 holder for 4x5 Polaroid film and the other is a Polaroid pack film holder. Buyer is welcome to the film, too, but I doubt it is worth anything. The 4x5 expired in '05 and '06 and the pack film appears to have an expiration of 1990...
No guarantee on any of this except that the photos are of the stuff you'll get.
I would think the holders alone would fit in a medium flat rate box at $10.70 shipping and it should all fit in a large flat rate box @ $14.50. I'll put it in the smallest flat rate bx that I can.
If you can use them, make me an offer... Paypal +$3 unless sent as a gift.
