Akron 1722 Turbojet 1.50NH Fire Nozzle - 11" Firefighter Department Equipment

Here's an Akron Turbojet 11" fire nozzle (11.3" overall). The rotating PSI collar appears to have a crack where the set screw is (see pics). It still rotates as it should, but I do not know if it will effect use of the nozzle (or if Akron would fix it?). This is a used piece of equipment that has some wear and scratches, but looks to be in great "physical" shape (other than the PSI collar). From the fire department - I was told that this works as it should - but that they were replacing some used equipment with new. Please look closely at the pictures for condition (I do not have the ability to independently test these).
