Very nice looking M577, Matthew. I like the weathering, and the stowage looks great. The antenna is also impressive--I bet this dio won't fit on a standard shelf!
I think you forgot to reattach the rear ramp pulley cable, however (it is hanging in mid-air in the 3rd and 4th pics).

Eduard PE razor wire set # 35640 It's not terribly expensive, but it isn't cheap, either. Look around and you might be able to find it for less at some other online store.
