HGU-53/P helmet

Message 25846, February 3, 2007:
Hi Pnutar et al, It appears that all production HGU-53/P helmets were made to the same 1988 contract but the configuration was updated through the production run. I have seen one manufactured in 1993 as well.
The main visual difference between the HGU-53/P versions is the visor operating mechanism. I have noted three different as seen in the attached picture. The first is a limited procurement helmet for operational test and evaluation, the second is an early production helmet (like the November 1991-dated one in the eBay auction) and the last a late production helmet (an August 1993 dated example was sold by 'navyfastjet' on eBay some time ago). The last version appears to be the most commonly found configuration.
Cheers, Bluelight

(Reference to eBay auction #190076158246) note the seller has a hgu53 with a 88 contract date but with a 91 making date by gentex?
