Petri-7s Light Seal Kit

$7.18
This USCamera custom light seal kit fits all Petri 7s rangefinder film cameras I've seen.  This foam light seal kit includes 2 door channel seals on the camera body and 1 hinge seal on the camera body. Please note.  The 1st models of Petri 7s are the  "Circle-Eye System' cameras.  Those cameras use that old standard furry yarny type material for the door channels and door hinge. I made this kit after many customers requested a foam kit to replace damaged, missing or moldy seals.   USCamera light seal placement guide for this Petri film camera here
