I started with the available hard plastic kits and tried to turn them into something more interesting (and possibly more realistic). Italeri makes two bunkers, one of which is actually a pretty accurate model of the H677 bunker. Both have no interiors, of course, and skinny little plastic walls. So I had to add thicker walls to make the interiors look less odd. I also added some infantry positions to the H677:




The other Italeri bunker is a strange, figure-8-shaped thing, which resembles no actual bunker that I know of. Here's what I did with it:



Most will remember that Airfix also made a couple of "big gun" emplacements, one called just "Gun Emplacement" and the other "Coastal Defense Fort". I've modified both of them pretty extensively. Here's the first:





Here's the other one:





The only other plastic kit suitable for the Atlantic Wall -- that I know of, at least -- was the thing by Arii called "German Secret Strong Point". I just used the main piece of the set:







Last, another "big gun", this one a pretty accurate representation of one of the gun positions in the Longues-sur-Mer battery. The front portion of the bunker was a plaster kit (whose maker I've forgotten). The rear and the interior I added:






When I have some more time, I'll post some photos of the smaller defenses I'm working on: pillboxes, AT positions, shelters, pits, and the like.
