Since I can't append a comment to the listing I tried to archive it before posting this. The result is at http://web.archive.org/web/201610121...on-Compure-100 Short answer, posts on this site can't be archived because archive.org can't log in to it.

I'm posting this because I don't trust the seller to pay attention to a PM.

The seller claims that a 75/4.5 MP-4 Tominon covers 4x5 at infinity. Polaroid, who should know, says that it covers 4x5 at magnifications greater than 2:1. 2:1 is a little closer than infinity.

The seller also claims that the lens is in a "compure press shutter." Spelling error aside, this is barely possible, but if so the lens is not an MP-4 lens. MP-4 lenses are in barrel, screw into the front of a #1. All Polaroid gelcam lenses are in shutter, usually Polaroid Copal #1 Press.
