The photos mentioned by Christian in "Butcher Bird" (Cerberus, 2003) on pages 78 & 142 are quite clear & sharp. Author states it's an A-4 although it's clear that it belongs to earlier types (probably A-3 with deleted outerwing armament).
As I can see on the page 78 - there is really an armed guard on the edge of the photo. Person in civilian clothes is next to him though that leather coat looks a bit intimidating.
On page 142 tail is not in the frame & on page 78 it's partially hidden behind the hat of the "civil" though last two digits look like ...00 (or some other round digits). A magnifying glass would help
especially on the original photo.
